Fix workspace-aware tool execution for Cursor agents

[hawkff]

Fixes #11

What

• Make plugin tool-hook execution context-aware by normalizing local tool args against session workspace (context.worktree / context.directory).
• Resolve relative path-like arguments to absolute workspace paths before executing handlers.
• Default bash/shell cwd to session workspace when cwd is omitted.
• Default grep/glob/ls path to session workspace when path is omitted.
• Add regression tests for:
  • relative write path resolution via tool context
  • bash default cwd from tool context

Why

Some Cursor agent runs infer the wrong working root and fail to write in the actual opened project when tool calls use relative paths or omit cwd/path defaults.

Grounding tool execution in session context keeps file/shell operations aligned with the active project/worktree.

Validation

• bun test tests/unit/plugin-tools-hook.test.ts
• bun run test:ci:unit
• bun run test:ci:integration
• bun run build

Cheers Max. PR #22 confirmed still relevant after the recent provider-boundary/schema changes, looks like it improves plugin tool-hook execution context (workspace-aware path/cwd normalization) in src/plugin.ts.

Review status:

• Clean merge against current main only touched:

  • src/plugin.ts
  • tests/unit/plugin-tools-hook.test.ts

• Merged to main (commit 6a25eb8).

• Post-merge checks passed:

  • bun test tests/unit/plugin-tools-hook.test.ts
  • bun run build
