chore(marketplace): re-pin thinking-framework-skills to v0.15.0

[jprisant]

Installers get the new build only after this merges.

sha e317da9 -> 5e44707 (the v0.15.0 tag commit)
version 0.14.0 -> 0.15.0
metadata 1.77.0 -> 1.78.0

What v0.15.0 contains

No new skills; the catalog stays 56 evidence-graded core skills + 7 contested lenses. 13 PRs
(#117-#129) in the upstream repo.

Everything the library publishes about itself is now either machine-asserted or measured by an
instrument that can actually see it. Four behavioural runs closed the last measurement gaps:

• All four entry-point tools reach maturity: measured. The fourth needed a purpose-built dispatch
  harness, because it delegates to a subagent and its own instructions forbid running research
  inline - so the generic harness could only ever have graded it breaking its own procedure.
• The front-door question ("does an agent with 77 tools installed reach for this library at all?") is
  measured and published as a distinct third question, never blended with the other two.
• The catalog-enrichment question is answered by a controlled single-variable A/B.
• The 63-skill artifact-quality figure was re-measured and went down, 428/429 -> 424/429, because
  the grader was rewritten to stop believing artifacts' claims about other skills. Published as-is,
  with the reason, rather than smoothed.

Four defects the runs found, all fixed: a score generator that rounded 99.5%+ up to a flat
100% (the cause of a false claim on the public trust page), a skill publishing the wrong evidence
tier for three months, a skill telling users to hand-roll a method this library ships, and the
rounding's knock-on effect of hiding a real false-fire result.

Contributor road: npm run setup takes a fresh clone to a green gate in one command, reading the
pinned validator commit out of CI so it cannot drift from what CI grades against. Issue and PR
templates encode the selection bar.

Conformance gate stays fifteen layers, 0 errors / 90 warnings at declared Standard 0.8 (the G9
docblock debt was paid off in full, 129 -> 90). Test suite 286 -> 326.

Verification

• sha is the exact commit the v0.15.0 tag points at (git rev-parse v0.15.0), not a branch head
• marketplace.json re-parsed as valid JSON after editing
• Upstream release: https://github.com/product-on-purpose/thinking-framework-skills/releases/tag/v0.15.0
