feat(hotpath): fill session-temporal-store query/persist gaps

[ScriptedAlchemy]

Summary

Fills the remaining hotpath coverage gaps in crates/tracedecay-session-temporal-store (HP-temporal), instrumentation only — no behavior changes, no Cargo.toml/feature changes, and hotpath stays opt-in (every macro is a no-op without the hotpath feature).

All labels follow the existing session_temporal.<area>.<verb> taxonomy. Getters, Display impls, tests, cfg(test) helpers, and pure delegations were skipped.

New instrumentation

File	Labels
operations/message_anchor.rs	publication.resolve_anchor, publication.anchor_occurrence, publication.anchor_observation
store.rs	store.persist_refresh_batch, store.persist_refresh_batch_controlled, store.refresh_recovery, store.refresh_running
query.rs	query.read_generation, query.read_active_generation, query.read_observation, query.read_observations
cursor_keys.rs	cursor_key.provision, cursor_key.load_active, cursor_key.load, cursor_key.keyring (sync)
execution.rs	execution.validate_report, execution.authorize_task_session (sync — file is a ports/types module with no async code)
retrieval/candidates.rs	query.root_authority, query.candidate_clause
sql.rs	sql.query (aggregate over every temporal retrieval read)
hydration.rs (add-missing)	hydrate.authorize, hydrate.read_authorized, hydrate.decode_message, hydrate.read_occurrence, hydrate.resolve_occurrence, hydrate.resolve_summary, hydrate.summary_evidence
projection/persist.rs (add-missing)	projection.record_count, persist.occurrences, projection.canonical_occurrence, projection.require_occurrence, projection.validate_copy, projection.validate_copy_proof, persist.assertion, projection.validate_assertion

Notes

• refresh.rs (add-missing target) needed no changes: every entry point already carries a measure; the only unmeasured async method (persist_session_refresh_projection_batch_result) is a pure delegation to the measured controlled variant, so adding a label there would only duplicate the session_temporal.persist.refresh_batch span.
• test_registered_impls.rs skipped as instructed.
• Row-decoding micro-helpers under already-measured entry points were left alone, matching the existing pattern in operations/generation.rs.

Verification

• cargo check -p tracedecay-session-temporal-store (default features) — pass
• cargo check -p tracedecay-session-temporal-store --features hotpath — pass (macros active)
• cargo clippy -p tracedecay-session-temporal-store --all-targets — clean
• cargo test -p tracedecay-session-temporal-store — 131 passed, 0 failed
• Commit subject passes commitlint.
