wiki: recompile overview.md + add /wiki-lint skill + /save unseeded check

overview.md recompiled with all 24 client articles and 7 project articles.
Captures ~80 action items sorted by priority; top urgent items: Neptune

.claude/commands/wiki-lint.md: new skill — scans clients/ and projects/
for directories with session-logs but no wiki article, checks broken
[[backlinks]], stale last_compiled dates, index gaps, and stale queue
entries. Emits a structured lint report.

.claude/commands/save.md: added Phase 4 unseeded-wiki check — after sync,
if the session log was written for a client/project with no wiki article,
emit a /wiki-compile reminder. Informational only, no blocking behavior.

+Health-check the wiki for missing articles, stale content, broken backlinks, and cross-reference gaps.
+
+Run this after any session where new session logs were created, or when starting a new session and the wiki may be out of date. Also run before any `/wiki-compile all` pass.
+
+---
+
+## Step 1 — Missing Articles (Primary Check)
+
+Scan for clients and projects that have session logs but no wiki article.
+
+```bash
+# List all client slugs that have session-logs but no wiki article
+cd D:/claudetools
+for dir in clients/*/session-logs; do
+  slug=$(echo "$dir" | sed 's|clients/||;s|/session-logs||')
+  wiki="wiki/clients/$slug.md"
+  if [ ! -f "$wiki" ]; then
+    count=$(ls "$dir"/*.md 2>/dev/null | wc -l)
+    echo "MISSING: $wiki  ($count session logs)"
+  fi
+done
+```
+
+```bash
+# List all project slugs that have session-logs but no wiki article
+for dir in projects/*/session-logs; do
+  slug=$(echo "$dir" | sed 's|projects/||;s|/session-logs||')
+  wiki="wiki/projects/$slug.md"
+  if [ ! -f "$wiki" ]; then
+    count=$(ls "$dir"/*.md 2>/dev/null | wc -l)
+    echo "MISSING: $wiki  ($count session logs)"
+  fi
+done
+```
+
+Report each missing article as:
+```
+[MISSING] wiki/clients/<slug>.md — <N> session logs, oldest: <YYYY-MM-DD>
+```
+
+Suggest: `Run /wiki-compile client:<slug> to seed.`
+
+---
+
+## Step 2 — Stale Articles
+
+Check `last_compiled` date in all wiki article frontmatter. Flag any article where:
+- `last_compiled` is more than 90 days ago AND there are session logs newer than `last_compiled`
+- Report as `[STALE]` with days since compile and count of new logs
+
+Use `grep -r "last_compiled:" wiki/` to collect dates, then compare against session log mtimes.
+
+---
+
+## Step 3 — Broken Backlinks
+
+Scan all `[[link]]` references in wiki articles. For each `[[slug]]`, check:
+- Does `wiki/clients/<slug>.md` exist? Or `wiki/projects/<slug>.md`? Or `wiki/systems/<slug>.md`?
+- If none match → flag as `[BROKEN_LINK]`
+
+```bash
+grep -rh '\[\[' wiki/ | grep -oP '\[\[\K[^\]]+' | sort -u
+```
+
+For each unique slug found, verify the file exists.
+
+---
+
+## Step 4 — Index Gaps
+
+Read `wiki/index.md`. For every `.md` file in `wiki/clients/`, `wiki/projects/`, `wiki/systems/`:
+- Is it listed in `wiki/index.md`? If not → flag as `[NOT_INDEXED]`
+
+Conversely, for every row in `wiki/index.md`:
+- Does the linked file actually exist? If not → flag as `[DEAD_INDEX_ENTRY]`
+
+---
+
+## Step 5 — Compilation Queue Cleanup
+
+Read the `## Compilation Queue` section in `wiki/index.md`. For each entry:
+- Does the corresponding `wiki/<type>/<slug>.md` file now exist? If yes → flag the queue entry as stale, suggest removing it.
+
+---
+
+## Output Format
+
+Emit a clean lint report:
+
+```
+## Wiki Lint Report — YYYY-MM-DD
+
+### Missing Articles (N)
+[MISSING] wiki/clients/evs.md — 1 session log (2026-04-17)
+...
+
+### Stale Articles (N)
+[STALE] wiki/clients/cascades-tucson.md — compiled 2026-05-24, 3 new logs since
+...
+
+### Broken Backlinks (N)
+[BROKEN_LINK] wiki/clients/kittle.md → [[gururmm]] (no file found)
+...
+
+### Index Gaps (N)
+[NOT_INDEXED] wiki/clients/new-client.md — not listed in index.md
+...
+
+### Compilation Queue — Stale Entries (N)
+[QUEUE_STALE] client:birthbiologic — wiki/clients/birth-biologic.md exists; remove from queue
+...
+
+### Summary
+- N missing articles → run /wiki-compile for each
+- N stale articles → run /wiki-compile to refresh
+- N broken links → fix manually or after recompile
+- N index gaps → update wiki/index.md
+```
+
+After the report, ask: "Run /wiki-compile for any of the missing articles now?"
