fix(providers): bound overlong tool wire names

[BillLeoutsakosvl346]

Summary

• Reuse existing provider-only aliases for unique and first-occurrence tool IDs longer than 64 characters.
• Preserve canonical IDs for execution, logs, forced selection, and instance-bound credentials; keep valid short IDs unchanged.
• Reuse existing collision handling and response/stream projection instead of renaming integrations or adding another naming framework.

Why

The existing duplicate-name aliaser already bounds generated names, but passed the first/unique overlong name through unchanged. Claude documents a 64-character tool-name limit: https://platform.claude.com/docs/en/agents-and-tools/tool-use/define-tools . This addresses length only, not a general character-policy redesign.

Validation

• 201 focused provider identity/binding/utility tests passed.
• App type-check, changed-file Biome, API validation, and git diff --check passed.
• Independent code review checked execution mapping, forced selection, collisions, and repeat-call stability.
• Only two existing files changed; one new regression case plus an updated boundary case.

Confidence Score: 5/5

The PR appears safe to merge because overlong wire IDs are bounded without disrupting canonical execution identity or existing valid IDs.

Summary

• Leaves valid IDs of 64 characters or fewer unchanged.
• Reuses existing collision avoidance and canonical-ID projection.
• Adds coverage for overlong IDs, reserved alias collisions, credential binding, and repeated assignment stability.
