Closes#3726.
## Root cause
Two coupled bugs in the ripgrep integration caused the glob and grep
tools to fail outright when the search path contained a broken
(dangling) symlink:
1. **Missing `--no-messages`** in `RG_FILES_FLAGS` (glob) and
`RG_SAFETY_FLAGS` (grep). ripgrep prints a stderr warning for every
broken symlink:
`rg: /path/to/broken-link: No such file or directory (os error 2)`
2. **Overly strict exit-code gate** in both `glob/cli.ts` and
`grep/cli.ts`: `if (exitCode > 1 && stderr.trim())` treated exit
code 2 as fatal and discarded the stdout, even though ripgrep exits
2 on *non-fatal* I/O issues (broken symlinks, permission denied)
while still printing valid results to stdout.
Combined effect: a single broken symlink anywhere in the search path
turned all subsequent file matches into an empty result with an error.
## Fix
- Append `--no-messages` to `RG_FILES_FLAGS` (`src/tools/glob/constants.ts`)
and to `RG_SAFETY_FLAGS` (`src/tools/grep/constants.ts`). This silences
ripgrep's non-fatal stderr warnings without changing match behavior.
- Relax the exit-code gate in both `glob/cli.ts` and `grep/cli.ts` from
`> 1` to `> 2`, matching ripgrep's documented contract:
- 0 = matches found
- 1 = no matches (success, just nothing matched)
- 2 = non-fatal I/O issues (partial success — stdout is still valid)
- >2 = fatal error
## Test changes
- New regression assertion in `src/tools/glob/cli.test.ts` for
`buildRgArgs` confirms `--no-messages` is included in the args.
- The grep change is symmetric (same flag, same rationale, same
exit-code constant) and rides on the parallel structure.
## Verification
- `bun test src/tools/glob/` → all pass (19 tests in cli.test.ts)
- `bun test src/tools/grep/` → all pre-existing tests still pass
- `bunx tsc --noEmit` → clean

Hoist shared ripgrep CLI resolution helpers (resolveGrepCli, resolveGrepCliWithAutoInstall, GrepBackend, DEFAULT_RG_THREADS, ResolvedCli) out of src/tools/grep/constants.ts into src/shared/ripgrep-cli.ts so they no longer straddle two sibling tool directories.
Before: src/tools/glob/constants.ts re-exported from src/tools/grep/constants.ts, violating the project's "tools should not import from sibling tools" rule enforced by .sisyphus/rules/modular-code-enforcement.md.
After: both src/tools/glob/ and src/tools/grep/ consume the shared helpers from src/shared/ripgrep-cli.ts. src/tools/grep/constants.ts keeps only the grep-specific UI-exposed constants.

The auto-download mechanism for ripgrep existed but was never called.
When 'rg' wasn't in PATH, the grep tool silently fell back to GNU grep,
which wastes ~10% token budget due to noisy results.
Changes:
1. Wired up resolveGrepCliWithAutoInstall() in the CLI resolution path
2. When 'rg' is not found in PATH, auto-downloads ripgrep v14.1.1
3. Caches the downloaded binary in OpenCode data directory
4. Falls back to GNU grep only if auto-download fails (with warning)
Fixes#3003
- Add --threads=4 flag to all rg invocations (grep and glob)
- Add global semaphore limiting concurrent rg processes to 2
- Reduce grep timeout from 300s to 60s (matches tool description)
- Reduce max output from 10MB to 256KB (prevents excessive memory usage)
- Add output_mode parameter (content/files_with_matches/count)
- Add head_limit parameter for incremental result fetching
Closes#2008
Ref: #674, #1722
Port ripgrep auto-installation feature from original OpenCode (sst/opencode).
When ripgrep is not available, automatically downloads and installs it from
GitHub releases.
Features:
- Platform detection (darwin/linux/win32, arm64/x64)
- Archive extraction (tar.gz/zip)
- Caches binary in ~/.cache/oh-my-opencode/bin/
- New resolveGrepCliWithAutoInstall() async function
- Falls back to grep if auto-install fails
