* 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.

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
