refactor(agent-core): use ripgrep for Glob tool (#1068)

* refactor(agent-core): use ripgrep for Glob tool

Glob now shares Grep's ripgrep subprocess plumbing: it respects .gitignore by default, supports brace patterns natively, adds an include_ignored option, and returns only files.

* fix(glob): address review findings on ripgrep migration

- Run rg with cwd pinned to the search root so glob patterns containing
  a slash (e.g. src/**/*.ts) match under an absolute search root.
- Keep include_dirs as a deprecated, ignored parameter so older calls
  are not rejected by parameter validation.
- Surface stdout truncation and drop half-written trailing paths when
  the rg output buffer is capped.
- Document that a bare pattern (e.g. *.ts) matches recursively, and sync
  user docs, the explore profile prompt, and the TUI summary to the new
  files-only / gitignore behavior.
- Add real-ripgrep integration tests covering sort order, recursion,
  brace patterns, and the absolute-search-root case.

* fix(glob): keep partial results on traversal errors

 **`Grep`** invokes ripgrep to search file contents, supporting regular expressions (`pattern`), a search path (`path`), file type filtering (`type`, e.g., `ts`, `py`), glob filtering (`glob`), and output mode (`output_mode`: `files_with_matches` / `content` / `count_matches`; defaults to `files_with_matches`). `content` mode supports context lines (`-A`, `-B`, `-C`), case-insensitive matching (`-i`), line numbers (`-n`, default true), and multiline matching (`multiline`). All modes support `offset` + `head_limit` pagination; `head_limit` defaults to 250 and `0` means unlimited. Sensitive files such as `.env` files and private keys are automatically filtered out; set `include_ignored=true` to search files ignored by `.gitignore`, though sensitive files remain filtered.
 
-**`Glob`** matches files in a specified directory (`path`; defaults to the working directory) by glob pattern (`pattern`). Results are sorted by modification time in descending order, with a maximum of 1000 entries. Pure wildcard patterns (e.g., `**`) and patterns containing brace expansion (`{a,b,c}`) are rejected.

Results are sorted by modification time in descending order, with a maximum of 100 entries. It respects `.gitignore`, `.ignore`, and `.rgignore` by default; set `include_ignored=true` to include ignored files such as build outputs, while sensitive files remain filtered. Brace patterns such as `*.{ts,tsx}` are supported, and broad wildcard patterns are allowed but usually truncate at the match cap.
 
 **`ReadMediaFile`** sends an image or video to the model as multimodal content. Accepts only `path`; the file size limit is 100 MB. Availability depends on the current model's vision capabilities (`image_in` / `video_in`).
