WalkthroughSearch-file filtering was changed so filterByFilepaths values are treated as regular expressions matched against full file paths; code and descriptive text were updated to stop escaping provided filepaths before inserting them into file: filters. Changes

In `@CHANGELOG.md`:
- Around line 10-11: The changelog entry for `filterByFilepaths` in the MCP
`search_code` tool is a bug fix and should be moved from the `### Changed`
section to `### Fixed`; update the header for that bullet to `### Fixed` (or
move the bullet into the existing `Fixed` section) and ensure the `-
filterByFilepaths ...` line appears at the bottom of the `Fixed` section per
CHANGELOG/CLAUDE.md conventions, preserving the PR/issue link and exact wording.
In `@packages/web/src/features/mcp/server.ts`:
- Line 150: The filepath filter in packages/web/src/features/mcp/server.ts
currently treats values as regexes; make it consistent with the other builders
by escaping filepaths as literal strings before composing the query: when
building the clause that uses filterByFilepaths (the line constructing query
with `file:${filepaths.join(' or file:')}`), map each filepath through
escapeStringRegexp(file) (the same helper used in
packages/web/src/features/chat/tools.ts and packages/mcp/src/index.ts) and then
join; ensure this mirrors how repos are escaped so all three query builders use
escaped literal filepaths.
