[#3094] Derived the previous install state at run time instead of storing '.vortex-manifest.json' in the project.

[AlexSkrypnyk]

Closes #3094

Summary

FileManager::snapshotPreviousTemplate() downloads the version named by the project's README Vortex-X.Y.Z badge and renders it through PromptManager::renderAsInstalled() using answers discovered from the destination, so the hashes removeExcludedPaths() compares against are built in a temp directory instead of read from a .vortex-manifest.json committed in the consumer project.

The removed readManifest() merged hashes read from <destination>/.vortex-manifest.json, so the mechanism only worked when a consumer committed installer bookkeeping; a colleague's clone, a fresh clone or CI fell through to hashing the raw, unrendered download, where your_site token replacements and the web/themes/custom/your_site_theme directory rename leave 100 of the template's 442 shipped paths matching nothing in the tree.

After merge no install writes or reads .vortex-manifest.json, removeObsoletePaths() deletes a committed one from any destination whose README badge marks it as a Vortex project, and Utils/UpdateRegistry appends every project edit an update overwrites to .logs/vortex-update.md as ### <path> sections with fenced diff blocks; the set of paths an update selects for removal is unchanged, and no shipped template file is added or removed.

Before / After

BEFORE: previous state read from a file committed in the project
+------------------------------------------------------------+
| install/update run
|   |
|   v
| write .vortex-manifest.json (hashes) into the project root
|   |     (consumer must commit it for the next run,
|   |      or a fresh clone/CI, to see it)
|   v
| next run reads .vortex-manifest.json back from the destination
|   |
|   v
| missing or stale -> fall back to hashing the raw, unrendered
| previous-version download (token replacements and directory
| renames match nothing in the tree)
|   |
|   v
| update overwrites an edited project file silently,
| with no record of what was replaced
+------------------------------------------------------------+

AFTER: previous state rendered on demand, replaced edits logged
+------------------------------------------------------------+
| install/update run
|   |
|   v
| FileManager::snapshotPreviousTemplate() downloads the ref
| named by the README's Vortex-X.Y.Z badge
|   |
|   v
| PromptManager::renderAsInstalled() renders it through the
| handler pipeline using $discoveredResponses -- what the
| handlers found in the destination, NOT this run's answers
|   |
|   v
| hashed straight out of a temp directory: nothing is ever
| written to, or read from, the project
|   |
|   v
| update overwrites an edited project file -> UpdateRegistry
| appends the project's diff and the update's diff to
| .logs/vortex-update.md (gitignored, so no PR churn)
+------------------------------------------------------------+

Rendering with discovered answers rather than this run's is what keeps a deselection working: Tools::discover() reports the tools actually present in the destination, so a tool switched off in this run is still present in the rendered previous version, and its config file is therefore still recognised as template-owned and removable.

Changes

• FileManager: removed MANIFEST_FILE, writeManifest() and readManifest(); added $previousDir, $previousRef and $registryFile tracking plus getRegistryFile().
• snapshotPreviousTemplate() accepts an optional $render callback, invokes it against the downloaded directory and ref, and keeps the directory and ref for recordReplacedChanges().
• removeObsoletePaths() deletes a .vortex-manifest.json left behind by an earlier install, only when Config::isVortexProject() is true, so a destination that never ran Vortex keeps a file of its own with that name.
• PromptManager gains $discoveredResponses, populated in args() from $handler->discover(), in resolveOrPrompt() from a resolved value, and finally by asking each remaining handler directly so a conditional prompt this run skips (for example HostingProjectName when HostingProvider changes to none) is still discovered from the destination.
• normalizeResponses() is extracted from runPrompts() so both the collected responses and $discoveredResponses go through the same Profile/ProfileCustom, Theme/ThemeCustom, ProvisionType and Starter post-processing.
• New PromptManager::renderAsInstalled() clones the config, points it at the downloaded directory and the previous ref, and runs the processors with the discovered responses.
• InstallCommand passes a closure into snapshotPreviousTemplate() that calls renderAsInstalled(), and passes $this->fileManager->getRegistryFile() into $this->presenter->footer().
• New Utils/UpdateRegistry: add() records a path's previous, project and next content, taking a nullable previous so a path the running version never shipped is distinguished from one it shipped empty; write() appends a ## <from> to <to>, <time> section to .logs/vortex-update.md; renderEntry() and renderDiff() build ### <path> entries with sebastian/diff, noting binary content or content over MAX_DIFF_BYTES (100KB) instead of diffing it.
• renderDiff() sizes the code fence from the longest backtick run in the rendered diff, because a unified diff prefixes an unchanged line with a single space and Markdown reads that as a closing fence, so a fenced block inside a diffed README.md or docs/ page would otherwise end the entry early.
• FileManager::recordReplacedChanges() walks the staged copy before the overlay and calls UpdateRegistry::add() for every path whose project content differs from both the previous version and the incoming version.
• InstallerPresenter::footer() takes an optional $registry_file and prints its relative path when one was written.
• .vortex/docs/content/updating-vortex.mdx step 3 now mentions .logs/vortex-update.md.
• InstallExcludedPathsTest rewritten from a manifest-stub data provider into real two-install update cycles against a real template ref (via Git::getLastShortCommitId()), covering unmodified and modified excluded paths, project-authored paths, replaced-change recording and stale-manifest removal, and asserting that composer.json and a file under the renamed theme directory are absent from the registry.
• New UpdateRegistryTest covering empty writes, both-diff rendering, unchanged-update omission, binary and oversized notes, project-authored paths, an empty installed file, fence widening, path ordering and appending to an existing file.
• FileManagerTest: stubManifest() replaced by stubPreviousTemplate(), which stubs a RepositoryDownloader instead of writing a JSON file, plus new tests for rendered-token exclusion, this-run deselection, replaced-change recording, stale-manifest removal and manifest retention on a non-Vortex destination.
• .vortex/tests/phpunit/Functional/InstallerTest.php asserts .vortex-manifest.json is absent instead of present.
• _baseline/.ignorecontent no longer lists .vortex-manifest.json.

Walkthrough

The installer now derives previous state from a rendered template reference instead of .vortex-manifest.json. It records overwritten project changes in .logs/vortex-update.md, removes obsolete manifests, reports the registry path, and adds unit and functional coverage.

I hop through templates, swift and bright
Old hashes fade into update light
A tidy log records each change
No manifest hops across the range
The installer hums, then rests

Inline comments:
In @.vortex/installer/src/Prompts/PromptManager.php:
- Line 266: Update the response-tree handling in PromptManager around
normalizeResponses and renderAsInstalled so the previous installation’s
conditional responses are discovered independently before snapshot rendering. Do
not merge current-run responses as fallbacks for undiscovered prior values;
ensure the complete previous-response tree is passed to runProcessors and
snapshotPreviousTemplate.

In @.vortex/installer/src/Utils/FileManager.php:
- Line 407: Update copyFiles() and removeObsoletePaths() so
.vortex-manifest.json is deleted only when Config::isVortexProject() indicates a
Vortex update; preserve the existing cleanup behavior for Vortex projects while
leaving user-owned manifests untouched during fresh installs into non-Vortex
destinations.

In @.vortex/installer/src/Utils/UpdateRegistry.php:
- Line 169: Update the diff-rendering method around the current fenced return to
compute the longest consecutive backtick run in the generated diff, choose a
fence longer than that run (with at least three backticks), and use the same
dynamic fence for both opening and closing markers while preserving the diff
language label and surrounding newlines.
- Around line 132-136: Update FileManager::recordReplacedChanges() and
UpdateRegistry::renderEntry() to preserve a separate flag indicating whether the
previous-template path existed, including when its content is empty. In
renderEntry(), branch on that existence flag rather than previous === '', and
for an existing empty previous file retain the project-versus-previous diff
alongside the project-to-next diff; only report that the running version did not
ship the file when the path is actually missing.
