No parent/child path resolution - subdirectory queries fail

[Retengart]

Problem

get_indexing_status and search_code use exact string matching on paths. Querying a subdirectory of an indexed codebase returns "not indexed".

Steps to Reproduce

1. Index /home/user/project
2. Query status for /home/user/project/src
3. Returns "not indexed" even though parent is indexed

Current Behavior

// handlers.ts:451-452
const isIndexed = this.snapshotManager.getIndexedCodebases().includes(absolutePath);

Exact string match - no parent traversal.

Expected Behavior

If queried path is a subdirectory of an indexed codebase, recognize it as part of indexed content.

Location

• packages/mcp/src/handlers.ts:451-462 - search_code check
• packages/mcp/src/handlers.ts:722 - get_indexing_status check
• packages/mcp/src/snapshot.ts:405-409 - getCodebaseStatus()

Suggested Fix

Before exact match, check if queried path starts with any indexed codebase path (normalized, with trailing slash handling).
