fix(vscode): keep Agent Manager .kilo out of git in subdirectory workspaces

[marius-kilocode]

What Problem This Solves

The Agent Manager could leave a .kilo directory untracked in a project.

• In a workspace that is a subdirectory of a git repository, the git exclude step failed (resolveGitDir required .git at the workspace root) and the anchored patterns never matched the nested path, so .kilo/worktrees/ showed up in git status.
• In a folder that was not a git repository, the worktrees directory was created before exclusion was attempted, so a later git init and commit could include it.

Why This Change Was Made

• ensureGitExclude now asks git for the exclude file and the repository-relative prefix (--path-format=absolute --git-path info/exclude and --show-prefix), so ignore patterns are anchored to the real .kilo location for subdirectory workspaces and linked worktrees.
• reconcilePool and createWorktree exclude before creating .kilo/worktrees, so a repository that cannot be excluded leaves nothing behind.
• addExcludeEntry matches whole lines instead of substrings, so a prefixed entry such as packages/app/.kilo/worktrees/ no longer suppresses the unprefixed repo-root entry.

Shared project config under .kilo/ (kilo.jsonc, agents, commands, rules) remains tracked.

User Impact

Opening the Agent Manager no longer pollutes git status in subdirectory workspaces and no longer creates .kilo in folders that are not git repositories.

Evidence

Behavior verified by driving the real WorktreeManager against fresh repositories:

Workspace state	Before	After
Repo root, clean	clean	clean
Repo with no commits	clean	clean
Repo with existing .git/info/exclude	clean	clean
Repo with .kilo/ in .gitignore	clean	clean
Linked worktree	clean	clean
Subdirectory of a repo	?? sub/.kilo/worktrees/.metadata_never_index	clean (!! sub/.kilo/...)
Non-git folder	.kilo/ created	.kilo/ not created

Automated checks:

• bun test tests/unit/worktree-manager.test.ts (134 tests, 2 new)
• bun test tests/unit/agent-manager-arch.test.ts
• bun run lint
• bun run typecheck

WARNING

File	Line	Issue
packages/kilo-vscode/src/agent-manager/WorktreeManager.ts	1101	git rev-parse echoes unrecognized options with exit code 0, so --path-format=absolute yields a contaminated/relative path on Git < 2.31; the exclude write then targets a bogus location and the original .kilo leak silently persists.
