v1.23: copy-mode/idle guards in daemon, xclip-only on Mutter, lint sweep

Daemon paste pipeline now survives the three silent-drop cases that made
paste look "broken" after v1.21 on this box:

  1. Wheel-scrolled pane (copy-mode active). cancel_copy_mode_if_active()
     exits copy-mode before sending \026; otherwise copy-mode's key
     handler swallowed the byte and the user saw no paste.
  2. Claude Code TUI mid-generation. wait_for_pane_idle() polls the
     pane's rendered text for the live `↓ N tokens` counter and holds
     the dispatch (cap 30 s) until the counter goes away. The TUI
     freezes its input handler during generation; the \026 byte was
     dropped on the floor before.
  3. Burst of right-click → Paste presses while the guard above is
     waiting. ipc.rs:handle_paste sets a `paste_in_flight` atomic so
     additional presses are deduped instead of queued. Without this,
     4 queued presses all fired \026 back-to-back the instant Claude
     unblocked (observed in journalctl with elapsed_ms 1853, 7600,
     16245, 26733 firing within a single second).

Other daemon-side changes bundled in:

  * kitty.rs: dispatch matches `state:active` instead of `state:focused`.
    Survives the focus steal from screenshot tools, right-click menus,
    and other transient focus changes. `state:focused` matched nothing
    when kitty had no OS focus at the exact moment of dispatch.
  * wayland.rs: latch `WAYLAND_WEDGED` once the compositor proves it
    speaks no `ext-data-control` / `wlr-data-control` (Mutter on
    GNOME 46). Subsequent re-asserts skip the doomed `copy_multi`
    spawn_blocking task entirely.
  * state.rs: staged-image TTL 2 min → 30 min so the AFK-then-paste
    case (screenshot, switch away, come back) doesn't silently demote
    Tier 3 → bash. Also corrects the Ctrl-V rebind to match the
    documented `flashpaste-trigger || dispatch.sh` pattern — previously
    the daemon rebound to bash-only after the first paste.
  * main.rs: `rt.shutdown_timeout(500ms)` so the blocking selection
    owners don't keep the tokio runtime alive past systemd's
    stop-sigterm. Eliminates the 90 s `deactivating` window where
    the socket exists but the listener is gone, which is when
    `flashpaste-trigger` was returning ECONNREFUSED after restarts.

bash side:

  * bin/clipboard-set.sh: gate the `wl-copy` path behind
    `FLASHPASTE_USE_WL_COPY=1`. On Mutter it spawned 4–5 extra forks
    per paste AND raised phantom "Unknown" dock icons, all without
    becoming a durable selection owner (no data-control protocol).
    xclip stays the durable owner; the wl-paste shim already routes
    through it. The block is marked AGENT-LOCKED with the full
    diagnosis so it isn't reverted on the next Mutter-doesn't-need-
    wl-copy refactor pass.
  * bin/flashpaste-logs.sh (new) + install.sh: unified live viewer for
    daemon journal + trigger log + clipboard-pipeline log. Symlinked
    as `flashpaste-logs` (no .sh) so the CLI surface matches
    flashpaste-trigger / flashpaste-doctor.
  * shellcheck: SC2163 in clipboard-set.sh:40 and get-clipboard-text.sh:50
    (`export "$kv"` → `export "${kv?}"`); SC2209 in flashpaste-trace.sh:162
    (`AWK_BIN=awk` → `AWK_BIN='awk'`).

Documentation:

  * Revert v1.22's `examples/tmux.conf.snippet` `-O` removal. The "TUI
    freezes until Escape" repro was on tmux <3.4 and does not hold on
    3.6a; removing `-O` instead caused the menu to auto-dismiss the
    instant the user moved the mouse toward an entry. `-O` restored.
  * markdownlint: bulk MD022/MD031/MD032 blank-line fixes via
    `markdownlint-cli2 --fix` across AGENTS / CHANGELOG / CONTRIBUTING /
    docs/adr/* / docs/*. MD040 fence-language tags added to 12 plain-
    text fences. docs/glossary.md entries promoted h3 → h2 (flat list,
    no intermediate h2). README "TL;DR for AI assistants" blockquote
    heading converted to bold (was h3 skipping h2). .markdownlint.json
    sets `MD025.front_matter_title=""` so frontmatter `title:` no
    longer clashes with body h1, and disables MD060 (not enforced by
    the CI action's bundled markdownlint).

Verified: tracked-file markdownlint clean (0 errors), bash -n clean
on all touched .sh files, cargo build --release clean (7 dead-code
warnings only).

+
+### Added
+
+- `bin/flashpaste-logs` — unified live viewer across the three streams the pipeline writes to (daemon journal, trigger log, clipboard-pipeline log). Colorized, prefixed, grep / since / -n / no-follow flags. `install.sh` symlinks it without the `.sh` suffix to match the muscle memory of `flashpaste-trigger` / `flashpaste-doctor`.
+
+### Changed
+
+- `rs/flashpasted/main.rs` bounds the tokio runtime drop with `shutdown_timeout(500ms)`. Without it, the blocking selection-owner threads kept the runtime alive forever, leaving systemd in `deactivating (stop-sigterm)` until the 90 s `TimeoutStopSec` SIGKILL — during which the socket file existed but the listener was already torn down, so `flashpaste-trigger` got ECONNREFUSED and the user saw paste as "broken after every restart."
+- `rs/flashpasted` paste pipeline now cancels copy-mode before sending `\026` (a wheel-scrolled pane silently swallowed the byte) and waits up to 30 s for the Claude Code TUI to finish generating (detected by the live `↓ N tokens` indicator) so pastes during generation no longer drop on the floor.
+- `rs/flashpasted/ipc.rs` adds an in-flight dispatch guard. While one dispatch is waiting for Claude to become idle, additional paste presses are deduped instead of queueing — previously 4 queued presses fired four `\026` bytes back-to-back the instant Claude unblocked.
+- `rs/flashpasted` kitty dispatch matches `state:active` instead of `state:focused` — survives the focus steal from screenshot tools, right-click menu rendering, and other transient focus changes.
+- `rs/flashpasted` latches `WAYLAND_WEDGED` once the compositor proves it speaks no `ext-data-control` / `wlr-data-control` (Mutter on GNOME 46): subsequent re-asserts skip the doomed `copy_multi` task entirely instead of spawn-blocking on every paste.
+- `rs/flashpasted` staged-image TTL bumped 2 min → 30 min so the AFK-then-paste case (screenshot, switch away, come back) doesn't silently demote Tier 3 → bash.
+- `rs/flashpasted` Ctrl-V rebind now matches the documented `flashpaste-trigger || tmux-paste-dispatch.sh` fallback. Previously the daemon rebound to bash-only after the first paste, silently demoting the rest of the tmux session to Tier 1.
+- `bin/clipboard-set.sh` gates the `wl-copy` path behind `FLASHPASTE_USE_WL_COPY=1`. On Mutter the wl-copy fork costs ~4–5 extra execs per paste AND surfaces phantom "Unknown" dock icons, all without acting as a durable selection owner (no data-control protocol available). xclip remains the durable owner.
+
+### Fixed
+
+- shellcheck SC2163 in `bin/clipboard-set.sh:40` and `bin/get-clipboard-text.sh:50` (`export "$kv"` → `export "${kv?}"`).
+- shellcheck SC2209 in `bin/flashpaste-trace.sh:162` (`AWK_BIN=awk` → `AWK_BIN='awk'`).
+- markdownlint: bulk MD022 / MD031 / MD032 blank-line fixes via `markdownlint-cli2 --fix` across `AGENTS.md`, `CHANGELOG.md`, `CONTRIBUTING.md`, `docs/adr/*`, `docs/*`. MD040 fence-language tags added to 12 plain-text fences. `docs/glossary.md` entries promoted h3 → h2 (flat list, no intermediate h2). README "TL;DR for AI assistants" blockquote heading converted to bold (was h3 skipping h2). `.markdownlint.json` sets `MD025.front_matter_title=""` so YAML frontmatter `title:` no longer clashes with the body h1, and disables `MD060` (table-pipe spacing) which the CI action's bundled markdownlint version does not enforce.
+
+### Reverted
+
+- `examples/tmux.conf.snippet`: v1.22 dropped the `-O` flag from the right-click menu binding on the theory that `-O` froze the TUI pane until Escape. That repro was on tmux <3.4 and does not hold on 3.6a; removing `-O` instead caused the menu to auto-dismiss the instant the user moved the mouse toward an entry. v1.23 restores `-O` so the menu stays open until item-click, click-outside, or Escape.

+#     leaves a phantom "Unknown" gear icon in the Ubuntu Dock for up
+#     to 5 minutes (until clipboard-janitor reaps).
+#   • Wayland clipboard is already WAYLAND_WEDGED on Mutter (latched
+#     in rs/flashpasted/src/wayland.rs — Mutter ships neither
+#     ext-data-control nor wlr-data-control). So wl-copy can't even
+#     act as a durable selection owner here. It was ALL COST, NO

+#   ✓ To re-enable on wlroots / KDE / a sway box where wl-copy works,
+#     export FLASHPASTE_USE_WL_COPY=1 in the shell that calls this.
