docs(release): finalize the v1.8.0 changelog section

[scotej]

Cuts the release notes for v1.8.0 (minor: the range adds a new persisted setting, a new Settings row, and a three-state friends list — the same shape that earned minors for 1.5.0/1.6.0/1.7.0).

This must land before Release-prep can run: both release paths extract the body with scripts/changelog-section.sh, which matches ## <version>. With ## Unreleased in place, changelog-section.sh 1.8.0 exits 1 — on the one-click path that aborts before the bump/tag/push (fails safe), but on the manual path it fails after the tag is immutable, stranding a pushed tag with no build.

Two corrections, because this text ships verbatim as the Release body

• A false developer claim. The notes said fresh checkouts "build and run" without scripts/fetch-llama-server.sh. src-tauri/build.rs:41-55 writes a debug-only placeholder and its release arm panics on it — so a release-profile build still requires the script, exactly as README.md:330-336 says. The changelog was contradicting our own README. Rewritten into a ### For developers section that matches.
• A wrong download size. "~10–20 MB" appeared in the notes, the in-app Settings row (src/strings.ts), and a store comment. Measured live against the pinned tag-b9095 assets: 8,643,613 B (macos-arm64) to 16,054,993 B (win-cpu-x64). All three now read 8–16 MB, so the release notes, the in-app copy, and the actual bytes agree.

Three omissions added

• The idle network-footprint increase from the I74 relay presence leg (one extra socket per pinned relay, a ~300-byte beacon every 30s, no off switch) — a friend deserves to know before auto-updating.
• The AI pane's rewritten privacy line (src/strings.ts), changed in this range but undocumented.
• A ### Known issue for the in-session Invite picker, which still renders a limited-connection friend as plain Available — a new failure mode I74 introduces. Deliberately shipped documented rather than fixed: batching a code change here would invalidate the CI-green-on-exact-SHA gate Release-prep requires. Filed for 1.8.1.

Also softened "direct connection proven" to account for LIMITED_CONNECTION_SETTLE_MS (120s), during which a relay-only friend renders plain green.

Verification

bash scripts/changelog-section.sh 1.8.0 → exit 0, non-empty body. prettier --check, check-strings, check-tokens, check-contrast, lint, build, and 871 tests all pass. No test or story asserts the old size string; Unreleased no longer appears anywhere in the tree.

Backed by a 22-agent readiness audit whose blocking findings each survived an independent adversarial refutation pass. It separately confirmed the release is safe to auto-deliver: no new SQLite migrations, an additive settings key with a tested absent→default path, an untouched updater pubkey/endpoint, untouched identity derivation, and a relay-presence namespace a 1.7.1 peer neither publishes nor subscribes.

src/**/*.{ts,tsx,css}

📄 CodeRabbit inference engine (CLAUDE.md)

src/**/*.{ts,tsx,css}: Frontend code must use design tokens rather than raw visual values; token compliance is enforced by scripts/check-tokens.ts.
Maintain WCAG AA contrast for every text/background pairing in both themes, provide information without relying on color alone, and respect the global reduced-motion kill switch.

src/**/*.{ts,tsx}

📄 CodeRabbit inference engine (CLAUDE.md)

src/**/*.{ts,tsx}: New motion sites must be gated by the global reduced-motion behavior by default.
Peer wire formats and identity derivation are cross-version contracts; coordinate changes so older peers remain compatible and stored identity/data are not stranded.
The application must remain local-only with no telemetry; never instruct users to paste model files or BIP39 mnemonics into an AI service.
Do not add comments unless the rationale is non-obvious; preserve established provenance tags such as I9, F6, or PR-27 when fixing traceable code.
Avoid unrelated refactors, hypothetical abstractions, and adjacent cleanup when implementing a feature or bug fix.
