Tom Boucher 722e1db116 fix: remove jq as undocumented hard dependency (#1300)
Add --pick flag to gsd-tools.cjs for extracting a single field from
JSON output, replacing all jq pipe usage across workflow and reference
files. Since Node.js is already a hard dependency, this eliminates the
need for jq on systems where it is not installed (notably Windows).

Changes:
- gsd-tools.cjs: add --pick <field> global flag with dot-notation and
  bracket syntax support (e.g., --pick section, --pick directories[-1])
- Replace 15 jq pipe patterns across 6 workflow/reference files with
  --pick flag or inline Node.js one-liner for variable extraction
- Add regression tests for --pick flag behavior

# Phase Argument Parsing
Parse and normalize phase arguments for commands that operate on phases.
## Extraction
From `$ARGUMENTS`:
- Extract phase number (first numeric argument)
- Extract flags (prefixed with `--`)
- Remaining text is description (for insert/add commands)
## Using gsd-tools
The `find-phase` command handles normalization and validation in one step:
```bash
PHASE_INFO=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" find-phase "${PHASE}")
```
Returns JSON with:
- `found`: true/false
- `directory`: Full path to phase directory
- `phase_number`: Normalized number (e.g., "06", "06.1")
- `phase_name`: Name portion (e.g., "foundation")
- `plans`: Array of PLAN.md files
- `summaries`: Array of SUMMARY.md files
## Manual Normalization (Legacy)
Zero-pad integer phases to 2 digits. Preserve decimal suffixes.
```bash
# Normalize phase number
if [[ "$PHASE" =~ ^[0-9]+$ ]]; then
# Integer: 8 → 08
PHASE=$(printf "%02d" "$PHASE")
elif [[ "$PHASE" =~ ^([0-9]+)\.([0-9]+)$ ]]; then
# Decimal: 2.1 → 02.1
PHASE=$(printf "%02d.%s" "${BASH_REMATCH[1]}" "${BASH_REMATCH[2]}")
fi
```
## Validation
Use `roadmap get-phase` to validate phase exists:
```bash
PHASE_CHECK=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" roadmap get-phase "${PHASE}" --pick found)
if [ "$PHASE_CHECK" = "false" ]; then
echo "ERROR: Phase ${PHASE} not found in roadmap"
exit 1
fi
```
## Directory Lookup
Use `find-phase` for directory lookup:
```bash
PHASE_DIR=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" find-phase "${PHASE}" --raw)
```
