• skills: resolve per-turn catalogs from turn input context (#26106)

  ## Why
  
  The skills extension needs the resolved turn environments to build a
  real per-turn `SkillListQuery`. The previous `TurnLifecycleContributor`
  hook only had a turn id, so it could only seed a placeholder query and
  never carry the executor authorities that executor-scoped skill routing
  will need.
  
  Moving catalog resolution onto `TurnInputContributor` puts the skills
  extension on the same turn-preparation path that already has the
  environment ids and working directories for the submitted turn, while
  keeping the actual prompt injection work for follow-up changes.
  
  ## What changed
  
  - switch `ext/skills` from `TurnLifecycleContributor` to
  `TurnInputContributor`
  - build `executor_authorities` from `TurnInputContext.environments` and
  pass them through `SkillListQuery`
  - keep storing the resolved catalog in `SkillsTurnState`, but drop the
  placeholder query helper that no longer matches the real data flow
  - update the extension TODOs to reflect that per-turn catalog resolution
  now happens in the turn-input contributor, and that prompt/context
  injection still needs to move later
  
  ## Testing
  
  - Not run locally.

• chore: extract context fragments into dedicated crate (#26122)

  ## Why
  
  `codex-core` currently owns the generic contextual-fragment trait and
  several reusable fragment implementations. That makes it harder for
  other crates to share the same host-owned model-input abstraction
  without depending on all of `codex-core`.
  
  This change extracts the reusable fragment machinery into a small
  `codex-context-fragments` crate so future extension and skills work can
  depend on the fragment abstraction directly.
  
  ## What Changed
  
  - Added the `codex-context-fragments` crate with:
    - `ContextualUserFragment`
    - `FragmentRegistration` / `FragmentRegistrationProxy`
    - additional-context fragment types
  - Moved `SkillInstructions` into `codex-core-skills`, since
  skill-specific rendering belongs with skills rather than generic core
  context machinery.
  - Kept `codex-core` re-exporting the fragment types it still uses
  internally, so existing call sites keep the same shape.
  - Updated Cargo and Bazel workspace metadata for the new crate.
  
  ## Verification
  
  - `cargo metadata --locked --format-version 1 --no-deps`
  - `just bazel-lock-update`
  - `just bazel-lock-check`
