docs: remove glob tool references from templates and skills

Update identity.md, TOOLS.md, skills README, and skill-creator
SKILL.md to remove mentions of the removed glob tool. Grep's
glob parameter remains documented where relevant.

-- **Best practice**: If files are large (>10k words), include grep or glob patterns in SKILL.md so the agent can use built-in search tools efficiently; mention when the default `grep(output_mode="files_with_matches")`, `grep(output_mode="count")`, `grep(fixed_strings=true)`, `glob(entry_type="dirs")`, or pagination via `head_limit` / `offset` is the right first step

 - **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.

-## glob — File Discovery
-
-- Use `glob` to find files by pattern before falling back to shell commands
-- Simple patterns like `*.py` match recursively by filename
-- Use `entry_type="dirs"` when you need matching directories instead of files
-- Use `head_limit` and `offset` to page through large result sets
-- Prefer this over `exec` when you only need file paths

 ## grep — Content Search
 
 - Use `grep` to search file contents inside the workspace
 - Default behavior returns only matching file paths (`output_mode="files_with_matches"`)
