fix(skills): reconcile team-template skill names so role bindings actually bind

Every skill reference in every team template was failing to resolve. The
TOMLs used snake_case slugs (`write_rust`, `index_selection`) while the
authored skills under `skills/**/*.md` declare kebab-case names
(`write-rust-current-edition`, `postgres-index-selection`), so
`get_by_name` missed on all of them: 128 skipped bindings across 51
distinct names, and no mission agent received any of its template's
skills.

The mirror-image half was equally invisible: ten authored skills —
including `int-xx-marker-protocol`, whose own `when_to_use` says "pin on
every coding role" — were referenced by no role at all, so nothing could
ever load them.

- Rename the 14 references that have authored skills behind them, and
  dedupe the two that now collapse onto the commit-protocol skill.
- Attach all ten orphaned skills to the roles their `when_to_use` names.
  All 23 authored skills now reach at least one role.
- Aggregate the loader's per-name logging into one line per template.
  The old per-name spam is why this went unnoticed; a bound/unresolved
  count is noticeable. References with no authored skill are kept and
  listed — they record intent for skills not yet written.
- Two regression tests: no authored skill may be orphaned, and every
  authored skill must be referenced by its exact name.

Also clears the two standing clippy warnings: group
`mint_team_from_template`'s eight positional args into `TeamMint`, and
make `provider_alias_for` branch on `is_exact_provider_match` so the
helper is live code and the two can't disagree about what counts as an
exact family match.
