skillscript-runtime v0.27.3

Upgrade impact: none (additive). One dashboard rendering fix + docs; no runtime behavior change.

• Dashboard: fixed the skill-source security highlighter leaking character offsets into the rendered body. The approval-review source viewer was showing stray numbers glued to mutation ops and approved= kwargs (e.g. $ data_write2861 … approved="…"3021). The highlight pass's single-capture-group patterns were treating String.replace's third callback argument — the match offset, a number — as a capture group, and rendering it. Fixed (typeof p2 === "string" guard); added a regression test that fails on the leak. The stored skill source was never affected — this was render-only.
• Adopter-facing docs audit (adopter-agent-guide.md, adopter-playbook.md, connector-contract-reference.md). Pre-announcement pass for accuracy + no internal leakage:
  • Removed internal-process references (thread ids, internal-agent names, dev-cadence/roadmap phrasing, an internal substrate name used as an example) and stripped version-provenance citations, keeping only the genuine v1.0 contract-version mentions.
  • Accuracy: the SkillStore contract block + ship-status table were missing manifest() (claimed 8 methods, listed 7) — corrected, and DataStore made consistent; the AgentConnector WakeReceipt interface block was missing warnings?: string[] — added; the agent-guide MCP tool reference completed from 13 to the full 17 tools.
• language-reference.md re-rendered from atoms — the # OnError: deprecation section now states removal is planned for a post-launch release (after 0.30), replacing the earlier reference to a version that will be skipped.
