centdix ce041e8a5e feat: hash-based MCP tool names for long paths (#8133)
* feat: replace _TRUNC with hash-based MCP tool names (50 char limit)

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix: reduce MCP tool name limit from 50 to 40 chars

* refactor: use path prefix filtering instead of separate DB query for hashed name resolution

* fix: remove long path warning from MCP token creation (hashing handles long names)

* refactor: unify tool prefix parsing and fix extract_path_prefix_from_hashed for Hs- names

- Replace `is_hashed_name` + `parse_hashed_name` with unified `parse_tool_prefix`
  that returns `(type_str, is_hub, is_hashed)` in one call
- Fix `extract_path_prefix_from_hashed` to dynamically determine prefix length
  (3 for `Hs-`, 2 for `S-`/`F-`) instead of hardcoding index 2
- Simplify `reverse_transform` to reuse `parse_tool_prefix`
- Add tests for invalid prefixes and `Hs-` prefix handling

* fix: respect favorites scope in hashed tool name resolution

* refactor: deduplicate MCP tool name resolution and rename get_path_or_id

- Extract `unescape_path` helper in transform.rs to deduplicate the
  3-step placeholder unescape logic
- Extract `find_matching_path` helper in runner.rs to deduplicate
  script/flow candidate matching via ToolableItem trait
- Remove verbose tracing::info! logs from hashed tool resolution hot path
- Fix doc comment referencing nonexistent `is_hashed_name` function
- Rename `get_path_or_id` to `get_transformed_path` for clarity
