feat(discord): add gateway channel flow in wasm (#944)

* feat(discord): restore gateway channel flow in wasm

* chore(discord): bump channel version to 0.2.1

* fix(discord): address review feedback on gateway channel PR

- Add #[serde(default)] to DiscordMessageMetadata for backward compat
  with old Option<String> serialized metadata
- Restore mention polling alongside Gateway (on_poll processes gateway
  events first, then runs poll_for_mentions if configured)
- Update on_respond to handle source_message_id with message_reference
  for mention-poll reply threading
- Implement Gateway presence status: dnd before pairing, online after
- Implement Gateway resume (OP 6) with session_id tracking, falling
  back to fresh identify on Invalid Session (OP 9)
- Extract WebsocketSessionState and spawn_websocket_poll to reduce
  nesting in start_websocket_runtime
- Simplify should_apply_dm_pairing tautology
- Remove completed plan docs
- Fix clippy items_after_test_module in extensions handler

* fix(discord): address review findings in gateway channel PR

- Fix gateway presence always showing "online" by filtering empty
  owner_id strings from workspace store reads
- Fix interaction followup using POST instead of PATCH to
  /messages/@original, which left deferred "thinking" state unresolved
- Restore mention-poll pagination (up to 5 pages of 100 messages)
- Remove dead ed25519-dalek and hex dependencies from WASM crate
- Remove unused _channel_id parameter from remember_processed_id
- Clean up redundant let binding in send_pairing_reply

* fix(discord): address second-round review findings

- Log warning when gateway event queue JSON fails to deserialize
  instead of silently returning empty (zmanian review item 1)
- Defer presence update from OP 10 Hello to after OP 0 READY, per
  Discord gateway protocol which requires READY before non-Identify
  commands (zmanian review item 2)
- Add 0-25% random jitter to websocket reconnect backoff per Discord's
  reconnection recommendations (zmanian suggestion)
- Extract WebsocketPollContext struct to replace 19-parameter
  spawn_websocket_poll function (zmanian suggestion)
- Document intent bitmask 4609 = GUILDS + GUILD_MESSAGES +
  DIRECT_MESSAGES in capabilities JSON (zmanian suggestion)

## Advanced Usage
### Gateway Mode
The Discord channel now defaults to Discord Gateway transport for inbound message intake.
The bundled identify payload requests intents `4609`, which expands to:
- `GUILDS` (`1`)
- `GUILD_MESSAGES` (`512`)
- `DIRECT_MESSAGES` (`4096`)
Gateway DMs now follow the same pairing policy as webhook DMs. Unpaired users receive a pairing
instruction reply in the DM channel before the message is allowed through to the agent. If you
want stricter access control than pairing, set `owner_id`; that lock still applies to both
webhook and Gateway traffic.
Gateway presence simply reflects a successful authenticated Gateway connection and advertises
`online`. Pairing still controls whether DMs are allowed through to the agent, but it no longer
changes the visible Discord status.
### Mention Polling
The Discord channel can also poll configured channels for `@bot` mentions.
@@ -110,6 +128,7 @@ Example channel config:
- `owner_id`: when set, only that Discord user can interact with the bot.
- `dm_policy`: `open` allows all DMs; `pairing` requires approval.
- `allow_from`: allowlist entries for DM pairing checks (`*`, user id, or username).
- Gateway DMs respect `dm_policy` and pairing just like webhook DMs.
