Restore workspace search on older Git

[prathamdby]

Summary

• Shared workspace search no longer passes git grep --max-count.
• Result and stdout-byte caps still apply after parse.
• Operator and development docs name Debian bookworm Git 2.39.x as enough.
• Workspace-tool tests cover a search path that contains a space.

Closes #556

Greptile Summary

This PR restores workspace search compatibility with Debian bookworm Git by removing the unsupported git grep --max-count argument while retaining post-parse result limiting and bounded subprocess output.

• Updates operator, configuration, development, cloud, and architectural documentation to identify Git 2.39.x as supported.
• Adds workspace-search coverage for paths containing spaces.
• Leaves the compatibility-specific behavior without a regression test against Git 2.39 or an equivalent unsupported-argument guard.

Confidence Score: 4/5

The implementation appears safe to merge, with a non-blocking test-coverage gap around the compatibility behavior being restored.

Removing the unsupported option restores the stated runtime compatibility, and existing byte and returned-result limits remain effective; however, the added test would not catch reintroduction of the incompatible argument.

Important Files Changed

Filename	Overview
src/prWorkspace/localPrWorkspace.ts	Removes git grep --max-count while preserving output-buffer truncation and post-parse result limiting.
test/localWorkspaceTools.test.ts	Adds path-with-spaces coverage, but does not directly enforce the older-Git compatibility behavior.
docs/adr/0012-full-context-local-pr-workspace.md	Records Git 2.39 compatibility and clarifies workspace-search budget semantics.
docs/configuration.md	Documents the search byte and result limits and the minimum Git runtime.
docs/operations.md	Connects the runtime image’s Debian Git version to workspace-search compatibility.

Prompt To Fix All With AI

### Issue 1
test/localWorkspaceTools.test.ts:486-504
**Compatibility regression is untested**

This test verifies that paths containing spaces work, but it would still pass if `--max-count` were reintroduced because CI uses a newer Git version. Add coverage that rejects unsupported arguments or run this search test against the documented Git 2.39 runtime so the restored compatibility remains enforced.
