refactor(flake): Consolidate overlay configurations into shared functions

Extract duplicated overlay and home-manager configuration code into two
reusable factory functions:

- mkBaseOverlay: Creates the base overlay with unstable pkgs, custom
  packages, and bitwarden-desktop compatibility. Accepts optional
  unstableOverlays parameter for darwin-specific customizations.

- mkHomeManagerConfig: Creates home-manager configuration with shared
  settings (useGlobalPkgs, useUserPackages, doom-emacs module). Accepts
  sharedModules parameter for platform-specific modules like plasma-manager.

This reduces code duplication across nixosModules, nixosModulesUnstable,
and darwinModules, making the flake easier to maintain and extend.

+---
+
+# Reconcile Beads Workflow
+
+This skill reconciles beads that are in `in_review` status with their corresponding PRs. If a PR has been merged, the bead is closed.
+
+## Prerequisites
+
+- Custom status `in_review` must be configured: `bd config set status.custom "in_review"`
+- Beads in `in_review` status should have a PR URL in their notes
+
+## Workflow
+
+### Step 1: Find beads in review
+
+```bash
+bd list --status=in_review
+```
+
+### Step 2: For each bead, check PR status
+
+1. **Get the PR URL from bead notes**:
+   ```bash
+   bd show [BEAD_ID] --json | jq -r '.[0].notes'
+   ```
+   Note: `bd show --json` returns an array, so use `.[0]` to access the first element.
+   Extract the PR URL (look for lines starting with "PR:" or containing pull request URLs).
+   Extract the PR number: `echo "$NOTES" | grep -oP '/pulls/\K\d+'`
+
+2. **Detect hosting provider**:
+   - Run `git remote get-url origin`
+   - If URL contains `github.com`, use `gh`; otherwise use `tea` (Gitea/Forgejo)
+
+3. **Check PR status**:
+   - For GitHub:
+     ```bash
+     gh pr view [PR_NUMBER] --json state,merged
+     ```
+   - For Gitea:
+     ```bash
+     tea pr list --state=closed
+     ```
+     Look for the PR number in the INDEX column with STATE "merged".
+     Note: `tea pr view [PR_NUMBER]` lists all PRs, not a specific one. Use `tea pr list --state=closed` and look for your PR number in the results.
+
+### Step 3: Close merged beads
+
+If the PR is merged:
+```bash
+bd close [BEAD_ID] --reason="PR merged: [PR_URL]"
+```
+
+### Step 4: Report summary
+
+Present results:
+
+```
+## Beads Reconciliation Summary
+
+### Closed (PR Merged)
+| Bead | PR | Title |
+|------|-----|-------|
+| beads-abc | #123 | Feature X |
+| beads-xyz | #456 | Bug fix Y |
+
+### Still in Review
+| Bead | PR | Status | Title |
+|------|-----|--------|-------|
+| beads-def | #789 | Open | Feature Z |
+
+### Issues Found
+- beads-ghi: No PR URL found in notes
+- beads-jkl: PR #999 not found (may have been deleted)
+```
+
+## Error Handling
+
+- **Missing PR URL**: Skip the bead and report it
+- **PR not found**: Report the error but continue with other beads
+- **API errors**: Report and continue
+
+## Notes
+
+- This skill complements `/parallel_beads` which sets beads to `in_review` status
+- Run this skill periodically or after merging PRs to keep beads in sync
+- Beads with closed (but not merged) PRs are not automatically closed - they may need rework
