fix: declare frameworkTier on the hover descriptor

[thymikee]

Summary

main's Coverage job is red at 142d156: #1786 added the public hover command without a frameworkTier, and #1804 (merged after) added the parity rule that every public descriptor declares one. Neither PR's own CI saw the combination. Every open PR's Coverage lane now fails on parity.test.ts > frameworkTier is declared iff a command is public.

hover is web-only pointer state, not part of the curated perceive/act loop, so it lands in 'extended' (the parity test's pinned 'core' set is unchanged).

Validation

Red on main (revert of this one-liner): AssertionError: hover declares frameworkTier iff it is a public command — 1 failed | 14 passed. Green with it: parity + ai-sdk suites pass; pnpm check:affected --run green (426 files / 3641 tests). One file touched.

Clean review at 5fe3492: hover is public and correctly declares frameworkTier: 'extended' at the descriptor source of truth, restoring the parity invariant without changing routing or runtime behavior. The revert-red proof is meaningful, exact-head CI and all platform smokes pass, and device evidence does not apply to this metadata-only repair. Ready-for-human.
