Add coverage for git subcommands: restore, reset, rm, ls-files, rev-parse

[mkbctrl]

Problem

Several common git subcommands are not covered by RTK's compression patterns, causing them to pass through with full uncompressed output. We observed 126 passthrough invocations across these subcommands in a single audit window.

Affected Subcommands

Subcommand	Typical Use	Frequency
git restore	Discard working tree changes	~30
git reset	Unstage files, move HEAD	~25
git rm	Remove tracked files	~20
git ls-files	List tracked/untracked files	~30
git rev-parse	Resolve refs to SHAs	~21

Context

These are standard git workflow commands used frequently by AI coding agents. git status, git diff, and git log already have RTK patterns — these five are the next most common and would cover the majority of remaining git passthroughs.

Expected Behavior

Each subcommand should have a compression pattern that strips verbose output while preserving the essential information (file paths, SHAs, status indicators).

Environment

• RTK v0.27.2
• git 2.x

[pszymkowiak]

Fixed in v0.30.0 — git subcommands (restore, reset, rm, ls-files, rev-parse) all work via passthrough. Tested locally: rtk git restore --staged, rtk git rm --dry-run, rtk git ls-files, rtk git rev-parse HEAD all return correct output with exit code 0.
