docs(skills): tighten dispatch prompt + add tool-failure failure modes (#593)

* docs(skills): tighten dispatch prompt + add tool-failure failure modes

Two changes from the 2026-04-28 overview-regen sweep retro (#590):

maintaining-orgs SKILL — the dispatch prompt template now:
- States the 250/300-word cap directly with a counter-example shape so
  sub-agents can self-check before returning.
- Tells agents to stop and surface fetch errors instead of regenerating
  from older data (paired with --wait, which is now exit-code aware
  after CLI #68).
- Forbids word-count notes / preamble / commentary outside the fenced
  block — the parent only harvests the block, but stray text was
  showing up in run logs.

regenerating-overviews SKILL — adds a "Don't Confabulate Around Tool
Failures" failure mode covering:
- Non-zero exit from `releases admin source fetch` → stop
- Surprising empty `overview-inputs` → surface, don't paper over
- No reading .env / no direct provider SDK calls
- No external data sources beyond `overview-inputs`

These were the actual root causes from the Apr 28 incident where the
OpenAI sub-agent generated from stale data and the Anthropic sub-agent
tried to read `.env` for ANTHROPIC_API_KEY.

* chore(skills): use 3-backtick fences in maintaining-orgs prompt template

Outer fence was 4 backticks to permit a nested ```markdown inner block.
Switch the inner block to a tilde fence (~~~) so the outer can be the
standard 3-backtick form.

Do NOT regenerate from older `overview-inputs` data — the result will be stale and the operator can't tell. The `--wait` flag added in CLI v0.10 makes this exit non-zero; trust the exit code.

Never read secrets of any kind. Never invoke provider SDKs directly. The model call described in step 2 is the parent's job, not a sub-agent's.
