feat(issue): add --status/-s to assign and take

[bougyman]

Summary

Implements CRY-60: allow lc issue assign and lc issue take to set a workflow state alongside the assignment in a single Linear issueUpdate mutation.

• Ash action: Extended :assign with an optional state_id argument; Issue.Update.Assign conditionally includes stateId in the mutation input
• CLI spec: Added --status/-s to both assign and take subcommands
• issue assign: Resolves status name case-insensitively against the issue's team workflow states before calling the API; unknown/ambiguous names exit 22 before any mutation fires
• issue take: Per-issue status resolution so different teams resolve the same name independently
• Already-assigned fix: take --status bypasses the self-assigned shortcut so the state is always updated
• Backward compatible: Omitting --status sends only assigneeId, exactly matching prior mutation shape

Examples

lc issue assign CRY-53 -a alice -s Todo
lc issue assign CRY-53 -a alice --status "In Progress"
lc issue take CRY-53 --status "In Progress"
lc issue take CRY-1 CRY-2 --status Todo

Test plan

• --status on assign: exact match, prefix match, case-insensitive, short -s
• --status on take: exact match, prefix match, case-insensitive, short -s
• Single mutation contains both assigneeId and stateId
• Assignment without --status sends only assigneeId (backward compat)
• Unknown status exits 22 before any mutation fires
• Already-self-assigned issue still updates status when take --status given
• Multiple issues from different teams resolve the same status name independently
• Bare issue number expansion with --status
• --output json returns structured output including state
• All 267 non-git tests pass
