EdisonJwa d2d9ba0a5b feat(diagnostics): A.3 — redacted in-memory log sink + user-initiated export
Replaces the diagnostics scaffold with the production redaction
policy + a user-initiated export path that satisfies DEC-016 (no
automatic uploads).

* `chanora_diagnostics::Redactor` applies the six policy rules to
  every captured log line: `$HOME` paths → `[home]`; IPv4 + IPv6
  literals → `[ip]`; email-shaped strings → `[email]`; long
  base64-ish tokens → `[token]`; substrings registered with
  `KnownSecretRegistry` → `[REDACTED]`. The registry implements
  SS-AUD-003 defence-in-depth: storage adapters can register
  secrets as they cross out of the keyring so an accidental
  `Debug` print is still scrubbed at write time.
* `InMemoryLogSink` is a bounded ring buffer (cap 500 lines in the
  bridge) that always passes lines through the redactor before
  storing them. `RedactingLogLayer` plugs it into `tracing-
  subscriber` alongside the existing logcat / fmt layers.
* `DiagnosticExport::from_sink` builds a plaintext blob — already
  redacted — combining free-form metadata (crate version, target
  os/arch) with the retained log tail. `bridge::api::
  export_diagnostics()` is the Flutter-facing entrypoint
  (`#[frb(sync)]`).
* `bridge_init` now installs the redaction layer on both Android
  and desktop hosts, switching from the global `fmt::init()`
  shortcut to a layered `Registry` so the in-memory sink can sit
  side-by-side with the platform sink.
* Flutter adds a bug-report icon to the AppBar; tapping it opens a
  scrollable monospace dialog with Copy and Close actions. New
  `diagnosticsAction` / `copyAction` / `closeAction` strings land
  in `app_en.arb` + `app_zh.arb`.

Tests cover the redaction matrix (IPv4, IPv6, email, long tokens,
known secret), the ring buffer capacity, and the full
`DiagnosticExport::to_text()` round-trip — 9/9 green.

Live-verified on Moto G: the dialog rendered a multi-line transcript
with `[ip]`, `[token]`, `[home]` substitutions, the metadata block
showed `target_os=android` `target_arch=aarch64`, and Copy placed
the same text on the clipboard.
