chore(release): v0.7.25

[argszero]

Summary

Release v0.7.25: ships the 18 PRs merged since v0.7.24 (#242-#259). No code changes of its
own — Cargo.toml/Cargo.lock version bump + CHANGELOG.md entry.

Two themes run through the release:

NFS performance on dev. Driven by host rant 2026-09-15T10:33:34 (/api/transactions
1.7-2.3s, /api/ops/runtime 2.1s). #259 removes the memory mapping (PRAGMA mmap_size 64MB -> 0)
and the per-request write (dao::touch_api_key gains a 60s guard) — the two mechanisms stack, so
neither alone pays off. #242 codifies the two emergency indexes in a v15 migration and gates the
conditional joins at the plan level. #243 reads the sharing page's earn total from one batched
aggregate instead of one query per row.

Frontend: display must equal what it filters on, and one fact, one source. #250 (one writer for
the transaction cache), #251 (clear every session slot at the identity boundary + give the wallet
view a loader), #253 (one shared writer for the wallet/dashboard month-changes), #254 (boot loads
only the destination view), #255 (a model row's identity is the model, not its array index), #256
(the marketplace source follows the session, not whether data arrived), #257 (the sidebar
advertises only digits that work), #258 (the admin total-balance card sums the gift amount its
caption names).

Plus i18n (#249, #252), forms and robustness (#244, #245, #246, #247, #248).

⚠️ Schema 14 → 15 (two covering indexes, applied at startup). No config.toml change, so
nothing to sync on the deployment side.

Changes

• Cargo.toml / Cargo.lock: 0.7.24 → 0.7.25.
• CHANGELOG.md: v0.7.25 entry describing all 18 PRs.
• No config/data-structure change beyond the schema migration already shipped in perf(db): codify the emergency transaction indexes and gate the conditional joins #242, so no
  example file to sync.
• ui/index.html cache-bust left as-is: the UI PRs in this release already advanced it past
  the value deployed with v0.7.24 (app.js 20260915-13, i18n.js 20260915-3).

Tests

• cargo test — 288 passed, 0 failed
• cargo fmt --check clean; cargo clippy --all-targets unchanged (only the pre-existing
  protocol.rs:662 warning)
• No new tests (version bump + docs only)
