tomdebone 4c71b76763 feat(tauri-app): X-style redesign — action bar, compose, tabs, sidebar, reply-mode
A two-pass rewrite of the home / compose / search / profile flows
to follow the X (Twitter) layout conventions while staying in our
monospace / orange-on-black terminal aesthetic. The WIP was
spotted by a parallel review agent which flagged 13 issues
(5 BLOCKER, 8 HIGH); a fix-pass agent then resolved them.

What changed
------------

**PostCard.svelte** — X-style action bar. Reply / repost / like /
view / bookmark / share buttons with live counts and orange
active-state fills. Liked / reposted states persist in
localStorage so the heart stays filled across reloads (the
AppView has no `viewer_liked` field yet). Hover shows the
action affordance. The whole-card click target is gone; the
action bar is the primary surface, and the body text is its
own button for 'view thread'.

**ComposeBox.svelte** — Avatar + textarea + bottom action row
with character counter and Post button. Counter uses
`Intl.Segmenter('en', { granularity: 'grapheme' })` so emoji
and ZWJ sequences count as 1 grapheme each (the atproto
`maxLength: 160` is grapheme-based, not UTF-16 code units).
`maxlength={MAX}` is set on the textarea itself so the browser
also enforces the cap. Counter flips through `counter` →
`counter--warn` → `counter--err` as the user approaches and
crosses the limit. Reply mode renders a 'Replying to @handle'
bar at the top of the compose card; the misleading
`@handle` prefix that *looked* like it was prepended to the
text is gone.

**Sidebar.svelte** (new) — 280px right-rail on the home view.
Three panels: a search shortcut (focus → switches to search
view), client-side trends (top 3 distinct authors in the
current timeline by post count), and a 'who to follow'
placeholder. Hidden below 900px viewport.

**App.svelte** — Home tabs (`for you` disabled + `following`
active, mirroring ProfileView's tab CSS exactly), search
tabs (`top` active, `latest` / `people` / `photos`
disabled, foundation laid for backend work), login card
centered with a brand title + tagline. New `replyTo` state
plumbs the reply click chain end-to-end.

End-to-end reply chain
---------------------

User clicks reply on a PostCard →
`PostCard.onReplyClick` → `fetchPost(uri)` to resolve
root / parent strongRefs → `onReply(target)` →
`App.svelte` sets `replyTo` + switches to compose view →
`ComposeBox` includes the `reply` block in `createPost` →
`post_create` Tauri command (lib.rs:112-150) attaches
`{root,parent}` strongRefs to the record body →
`PdsHttpClient::create_record` (pds_client.rs:214) writes the
post to the PDS with the reply block. The earlier WIP had a
visual '@handle' prefix that *looked* like it shipped with
the post text but didn't; this is now removed.

Review findings addressed
-------------------------

BLOCKER 1: Reply mode end-to-end. (B2-B5, H6-H13 trivial;
implementation agent handled all 13 in one pass.)

`Intl.Segmenter` counts emoji correctly (`🇯🇵` = 1 grapheme,
not 4 code units). All action buttons have `aria-label` +
`aria-pressed` where applicable; `disabled` is replaced with
`aria-disabled` + opacity so the buttons stay in the tab
order for keyboard users. The double-fire on avatar / author
is gone (the article no longer has `role="link"`, and
`openProfile` calls `event.stopPropagation()`). The
quoted-post null-guard crash is fixed with optional chaining.
Like / repost counts are derived from `post.like_count` +
a local optimistic delta so the value stays in sync when the
timeline poll rebuilds the post (also kills the two
`state_referenced_locally` warnings svelte-check was
flagging).

Verification
------------

* `cargo check --manifest-path crates/tauri-app/src-tauri/Cargo.toml` → 0 errors (2 pre-existing warnings).
* `npm run check` → 0 errors (2 pre-existing warnings: the `<details>` a11y in the post-menu kebab and one residual CSS unused-selector).
* `npm run test` → 20/20 passing (localStorage, client, NavRail).
* Reply chain end-to-end trace verified: PostCard `onReplyClick` → `fetchPost` → `on_reply` → App.svelte `replyTo` → ComposeBox `createPost` → Rust `post_create` → `create_record` → PDS.

Setup

# 1) Datenbanken + MinIO starten
docker compose up -d

# 2) Umgebungsvariablen
cp .env.example .env

# 3) Workspace kompilieren + Tests
cargo test --workspace
cargo check --workspace

# 4) Tauri-Frontend (Vite dev)
cd crates/tauri-app
npm install
npm run dev
# → http://127.0.0.1:1420

# 5) PDS / AppView (eigene Terminals)
