chore(knowledge): retire context-engineering blog doc-queue entry after slice completion

[kyle-sexton]

Summary

• Removes the new-rules-of-context-engineering blog entry from the docpage-digest Anthropic profile's doc queue — its slice completed end-to-end (fetch through interview handoff) per the queue's remove-on-completion rule.
• Channel: rendered (raw-md confirmed absent for this page — .md probe 404, Accept: text/markdown ignored — matching the profile's blog-post channel note); source.html unaltered original + firecrawl 1.19.27 markdown extraction, artifacts recorded in the slice checklist.
• Slice verification: Verifier A (same-vendor, fresh context) CORRECTION-NEEDED (1+3); Verifier B (cross-vendor Codex CLI 0.146.0 via the issue Restore cross-vendor Verifier B when openai/codex#32655 and #35871 are fixed (working invocation available now) #1740 elevated recipe, no degraded fallback) CORRECTION-NEEDED (10+1). All findings applied; cross-vendor re-verify round 1 resolved all 15 and surfaced 2 correction-introduced issues; round 2 REVERIFY2: PASS. Records under .work/claude-com-blog-the-new-rules-o-8e418fc0/verification/.
• Knowledge plugin 0.10.2 → 0.10.3 with matching CHANGELOG entry.

Verification

• markdownlint-cli2 on changed markdown: 0 errors
• check-skill.sh docpage-digest (CHECK_SKILL_SKILLS_ROOT=plugins/knowledge/skills, base origin/main): PASS (1 pre-existing soft warning, SKILL.md length)
• check-changelog-parity.sh --check-bump origin/main: PASS
• Independent fresh-context reviewer on the diff: APPROVE (traced the changelog claims to the slice checklist and verification records; its one non-blocking wording observation was applied before commit)
• Base freshness: fetched origin/main immediately before commit; zero commits behind

No security issues found.

This PR makes three changes, none of which introduce a security-relevant surface:

1. plugin.json — semver version bump 0.10.2 → 0.10.3. No code execution, no credential handling, no dependency changes, no trust-boundary effects.

2. CHANGELOG.md — prose documentation of the completed slice. No executable content, no secrets, no injection vectors.

3. anthropic-docs-profile.md — removes one URL entry from the doc queue list. The removed line is a plain markdown autolink to a public claude.com/blog page. No template expansion, no command interpolation, and no access-control or authorization implications follow from removing a queue entry.

The remaining URLs in the profile file are all to public Anthropic documentation properties (platform.claude.com, code.claude.com, claude.com/blog). No supply-chain or egress concerns.

Verdict: LGTM — no issues found.

The three-file diff is internally consistent and follows the established patterns for this plugin.

plugin.json — version bump
0.10.2 → 0.10.3: correct semver tier for a content-only change (no behavior, no interface, no schema delta). Matches the CHANGELOG entry exactly.

CHANGELOG.md — new [0.10.3] section
Lines 7–16: entry follows the same structure and level of detail as the prior two versions (0.10.1, 0.10.2). Channel selection rationale (rendered, raw-md probe 404), verification outcome summary (both verifiers returned corrections, all applied, cross-vendor re-verify PASS), and the triggering rule (remove-on-completion) are all documented. No gaps.

anthropic-docs-profile.md — queue removal
Two lines removed: only the completed entry is excised; the surrounding queue entries and file structure are undisturbed. The remaining queue entries (claude-models-explained, building-verification-loops) are still present and correctly formatted.

Cross-checks

• PR description's claimed verification results (markdownlint 0 errors, check-skill.sh PASS, check-changelog-parity.sh PASS) are consistent with the size and nature of the diff.
• No hardcoded paths, PII, or secrets introduced.
• Change is repo-agnostic (profile context file, not plugin engine).
