fix: resolve all CodeRabbit review comments

Critical fixes:
- GeminiCliHooksInstaller: wrap install/uninstall prep in try/catch to maintain
  numeric return contract
- McpIntegrations: move mkdirSync inside try block for Goose installer

Major fixes:
- import-xml-observations: guard invalid dates before toISOString()
- runtime.ts: guard response.json() parsing
- WorktreeAdoption: delay adoptedSqliteIds mutation until SQL succeeds
- CursorHooksInstaller: move mkdirSync inside try block
- McpIntegrations: throw on failed claude-mem block replacement
- OpenClawInstaller: propagate parse failure instead of returning {}
- OpenClawInstaller: move mkdirSync inside try block
- WindsurfHooksInstaller: validate hooks.json shape with optional chaining
- timeline/queries: pass normalized Error directly to logger
- ChromaSync: use composite dedup key (entityType:id) to prevent cross-type collisions
- EnvManager: wrap preflight directory/file ops in try/catch with ENV logging
