* feat(extensions): add load-time validation for auth capabilities
Catch common misconfigurations (missing auth section, missing setup_url,
short prompts) at startup via tracing::warn instead of silently failing
at auth time.
* feat(extensions): improve auth prompts, setup_url, and showAuthCard
Add setup_url and descriptive prompts to channel and tool capabilities
files. Fix showAuthCard in web gateway and improve extension manager
auth flow messaging.
* refactor(extensions): extract MIN_PROMPT_LENGTH constant in validate()
Address review feedback: replace magic number 30 with a named constant
for readability and maintainability.

* test: add failing tests for Discord signature validation and capabilities alias (Red phase)
TDD Red phase for #148. Adds 19 tests across 4 categories:
- Category 1: CredentialLocationSchema header_name alias (2 failing)
- Category 2: Ed25519 signature verification (3 failing)
- Category 3: Router signature key management (2 failing)
- Category 5: Discord capabilities public_key setup (1 failing)
All 8 failures are expected — stubs return false/None by design.
Implementation will follow in Green phase.

* fix: add Discord Ed25519 signature verification and capabilities alias (#148)
Implement the Green phase for Discord channel security fixes:
- Add real Ed25519 signature verification in signature.rs using ed25519-dalek
- Add #[serde(alias = "header_name")] to CredentialLocationSchema::Header
for backward compatibility with external JSON files
- Add signature_keys storage to WasmChannelRouter (register/get/unregister)
- Add discord_public_key to discord.capabilities.json setup.required_secrets
- Add nested capabilities resolution to CapabilitiesFile for channel-level
JSON compatibility

* style: address PR #372 review comments
- Fix invalid hex character in test fake_pub_key (router.rs)
- Simplify signature parsing with from_slice/try_from (signature.rs)
- Use idiomatic Option::or for nested capability merging (capabilities_schema.rs)

* fix: enforce signature verification, staleness check, key validation, recursive resolve
Address PR #372 review feedback:
- Wire verify_discord_signature() into webhook_handler with Ed25519
signature + timestamp staleness check (5s window via now_secs param)
- Validate Ed25519 keys in register_signature_key() (hex decode +
VerifyingKey::try_from) before storing, return Result<(), String>
- Recursively resolve nested capabilities in resolve_nested()
- Add 25 new tests: 8 staleness, 6 key validation, 7 webhook
integration (tower::oneshot), 4 resolve_nested edge cases
- Fix pre-existing clippy warning in signal.rs

* fix: wire register_signature_key() into all channel loading paths
The Ed25519 signature key registration was implemented and tested but
never called from production code. All three channel loading paths
(setup_wasm_channels, activate_wasm_channel, refresh_active_channel)
now read the public key from the secrets store and register it with
the webhook router, enabling Discord signature verification.
Adds `signature_key_secret_name` field to WebhookSchema so channels
can declare which secret contains their Ed25519 public key.

Port Telegram's permission model (owner_id, dm_policy, allow_from, pairing codes)
to Discord, Slack, and WhatsApp WASM channels. Add web UI for configuration and
pairing approval. Fix extension registry issues preventing Discord install and
causing Slack activation to hit the wrong endpoint.
WASM channels:
- Discord: add DiscordConfig, permission checks, ephemeral pairing replies,
fix capabilities.json (header_name→name), downgrade wit-bindgen to 0.36
- Slack: expand SlackConfig with permission fields, add check_sender_permission
and send_pairing_reply via chat.postMessage
- WhatsApp: expand WhatsAppConfig with permission fields, add permission checks
and pairing reply via Cloud API
- Telegram: reformat capabilities.json, add setup.required_secrets
Extension system:
- Add Discord to KNOWN_CHANNELS in bundled.rs and to extension registry
- Rename "slack" MCP→"slack-mcp", "slack-channel"→"slack" to fix name collision
- Add ExtensionSource::Bundled variant handling in discovery.rs
- Add get_setup_schema/save_setup_secrets to ExtensionManager
- Add needs_setup field to InstalledExtension
Web gateway:
- Add GET/POST /api/extensions/{name}/setup for configuration modal
- Add GET /api/pairing/{channel} and POST /api/pairing/{channel}/approve
- Add configure modal UI (password fields, provided badges, auto-generate hints)
- Add pairing request UI on active WASM channel cards
- Show "Restart to activate" label instead of Activate button for WASM channels
