Load a per-directory local overlay in addition to the base instruction
file, matching the Claude Code AGENTS.local.md / CLAUDE.local.md
convention for git-ignored personal guidance.
- New config `localInstructionFileCandidates`, default
`['AGENTS.local.md', 'CLAUDE.local.md']`; empty disables the overlay.
The default lives in the plugin Config schema, so every front door
(TUI/ACP/headless) reads .local. files consistently.
- Per project directory the plugin loads the first-existing base
candidate, then additively the first-existing local candidate,
rendered after the base so it takes precedence within the byte budget.
- Base and local tiers get distinct scope keys via a NUL sentinel
(scopeKey/decodeScopeKey) so they never collide in the baseline map,
pending window, or version cache.
- The fixed user-global $DSH_HOME/AGENTS.md stays base-only.
Docs: README (config, lifecycle, Known Limitations), regenerated
config-catalog, and a new bilingual Agent Note cross-linked to the
owning workspace-context note. 100% per-file coverage retained.
