Replace path.startsWith('/') with path.isAbsolute() in directory
injector hooks. The startsWith('/') check only works on Unix-like
systems where absolute paths begin with '/'. On Windows, absolute
paths start with drive letters (e.g., C:\), causing resolveFilePath
to incorrectly treat them as relative and prepend the project
directory.
This follows the same pattern already used in
src/features/claude-tasks/storage.ts (commit 8e349aa).
Affected hooks:
- directory-agents-injector: AGENTS.md injection
- directory-readme-injector: README.md injection
