feat(skills): Add import_gitea_issues skill for bead creation

Add a Claude Code skill that imports open Gitea issues as beads:
- Uses 'tea issues' to list open issues
- Checks existing beads to avoid duplicates
- Detects issue type (bug/feature/task) from content
- Creates beads with P2 priority and Gitea issue URL in notes
- Reports summary of imported vs skipped issues

Implements bead: nixos-configs-tdf

+# Import Gitea Issues as Beads
+
+This skill imports open Gitea issues as beads, checking for duplicates to avoid re-importing already tracked issues.
+
+## Prerequisites
+
+- `tea` CLI must be installed and configured for the repository
+- `bd` (beads) CLI must be installed
+- Must be in a git repository with a Gitea/Forgejo remote
+
+## Workflow
+
+### Step 1: Get open Gitea issues
+
+List all open issues using `tea`:
+
+```bash
+tea issues
+```
+
+This returns a table with columns: INDEX, TITLE, LABELS, MILESTONE
+
+### Step 2: Get existing beads
+
+List all current beads to check what's already imported:
+
+```bash
+bd list
+```
+
+Also check bead notes for issue URLs to identify imports:
+
+```bash
+bd list --json | jq -r '.[] | select(.notes != null) | .notes' | grep -oP 'issues/\K\d+'
+```
+
+### Step 3: Check for already-linked PRs
+
+Check if any open PRs reference beads (skip these issues as they're being worked on):
+
+```bash
+tea pr list
+```
+
+Look for PRs with:
+- Bead ID in title: `[nixos-configs-xxx]`
+- Bead reference in body: `Implements bead:` or `Bead ID:`
+
+### Step 4: For each untracked issue, create a bead
+
+For each issue not already tracked:
+
+1. **Get full issue details**:
+   ```bash
+   tea issue [ISSUE_NUMBER]
+   ```
+
+2. **Determine bead type** based on issue content:
+   - "bug" - if issue mentions bug, error, broken, fix, crash
+   - "feature" - if issue mentions feature, add, new, enhancement
+   - "task" - default for other issues
+
+3. **Create the bead**:
+   ```bash
+   bd add "[ISSUE_TITLE]" \
+     --type=[TYPE] \
+     --priority=P2 \
+     --notes="Gitea issue: [ISSUE_URL]
+
+   Original issue description:
+   [ISSUE_BODY]"
+   ```
+
+   Note: The `--notes` flag accepts multi-line content.
+
+### Step 5: Report results
+
+Present a summary:
+
+```
+## Gitea Issues Import Summary
+
+### Imported as Beads
+| Issue | Title | Bead ID | Type |
+|-------|-------|---------|------|
+| #5 | Add dark mode | nixos-configs-abc | feature |
+| #3 | Config broken on reboot | nixos-configs-def | bug |
+
+### Skipped (Already Tracked)
+| Issue | Title | Reason |
+|-------|-------|--------|
+| #4 | Update flake | Existing bead: nixos-configs-xyz |
+| #2 | Refactor roles | PR #7 references bead |
+
+### Skipped (Other)
+| Issue | Title | Reason |
+|-------|-------|--------|
+| #1 | Discussion: future plans | No actionable work |
+```
+
+## Type Detection Heuristics
+
+Keywords to detect issue type:
+
+**Bug indicators** (case-insensitive):
+- bug, error, broken, fix, crash, fail, issue, problem, wrong, not working
+
+**Feature indicators** (case-insensitive):
+- feature, add, new, enhancement, implement, support, request, want, would be nice
+
+**Task** (default):
+- Anything not matching bug or feature patterns
+
+## Error Handling
+
+- **tea not configured**: Report error and exit
+- **bd not available**: Report error and exit
+- **Issue already has bead**: Skip and report in summary
+- **Issue is a PR**: Skip (tea shows PRs and issues separately)
+
+## Notes
+
+- Default priority is P2; adjust manually after import if needed
+- Issue labels from Gitea are not automatically mapped to bead tags
+- Run this periodically to catch new issues
+- After import, use `bd ready` to see which beads can be worked on
