fix(skills): every team-template skill binding now resolves

55 of 85 role skill bindings pointed at skills that were never authored,
so 10 of 11 team templates bound a smaller context bundle than their role
prompts assumed. Three roles bound nothing at all (gpu.bench_engineer,
threejs.shader_author, threejs.perf_engineer) while their prompts described
procedures they had no way to read.

The loader comment at team_template_loader.rs:167 already diagnosed this —
snake_case slugs in TOML against kebab-case skill files — and it was
half-fixed: the kebab names were corrected, the snake_case ones left.

It was invisible because both existing tests assert authored ⊆ referenced
(30/30, green) and the second explicitly declines to check the other
direction. So the failing half was the half nobody asserted.

Resolved every name by one of three explicit choices:

  - 23 skills authored where the role genuinely needed the procedure
    (gpu, threejs, research, analysis, frontend, mobile, backend, platform)
  - renames onto authored skills where one existed in substance, including
    the four-near-duplicate cases that collapse onto one real skill
  - 22 aspirational references deleted — a binding an agent cannot read is
    a promise, not a capability

Two tests now hold it. The unit test checks referenced ⊆ authored against
the files. The new integration test runs both loaders in boot order and
asserts the bindings survive the trip through the database, which is a
different question: resolution goes through skills_catalog rows, so a skill
file that exists but fails to ingest still leaves the role empty.

Negative controls: the unit test failed naming all 55; the integration test
fails naming the exact role when one name is reverted.

threejs.shader_author and .perf_engineer gained a second and third skill
after the collapse — pin_in_context pins idx < 2, so a role left with one
skill silently pins less than the policy intends.
