feat(opencode-plugin): address Cubic PR #4 findings

[mislavivanda]

Summary by cubic

Improves reliability and safety across the Daytona plugin: shell-safe, per-repo serialized git operations; resilient sandbox reconnect/delete; safer on-disk storage; and clearer tool behavior. Fixes edge cases that caused failed syncs, stale sessions, or noisy errors.

• Bug Fixes and Hardening

  • Git: run git without a shell; serialize per-repo (git-common-dir, realpath) to avoid .git/config/index.lock races; add retries; pull the sandbox’s actual branch and only reset if it’s checked out; in the sandbox use checkout -f; fail fast if remote add/config fails.
  • Session/storage: sanitize projectId on disk via encodeURIComponent, decode on list; migrate by writing destination first and verifying; add read-only findSession and use it on delete (no migration); on update refresh worktree but preserve the canonical projectId; handle DaytonaNotFoundError on reconnect/delete, preserve mappings on transient errors; delete returns a boolean and clears stale mappings.
  • Tools/UX: validate edits (non-empty oldString, fail on missing/ambiguous matches), truncate grep to 100 matches with a note, validate preview port, report correct byte length on write, create bash exec session only when missing (rethrow non-404), and avoid duplicate error toasts on idle.
  • Paths/logging: fall back to ~/.local/share when XDG_DATA_HOME is unset, trim logs by bytes (not chars), and make logging best-effort.

• Removals and Docs

  • Removed unused lsp and patch tools; minor import cleanup and README updates on data path defaults, API key env var, and build/test instructions.
