Refactor command YAML headers: replace examples with argument-hint

**Summary:**
Updated all 62 command files in `.claude/commands` directory to improve parameter documentation clarity by replacing `examples` field with descriptive `argument-hint` field.

**Changes:**
- Added/improved `argument-hint` for all commands based on usage patterns
- Removed `examples` field and all example items from YAML headers
- Maintained all other YAML fields (name, description, usage, allowed-tools)
- Deleted obsolete commands: workflow/issue/*, workflow/session/pause.md, workflow/session/switch.md
- Cleaned up temporary analysis files

**Rationale:**
The `argument-hint` field provides clearer, more concise parameter documentation than example lists, improving command discoverability and usability in the Claude Code interface.

**Files Modified:** 62 command files
**Lines Changed:** -1570 insertions, +192 deletions
