v0.5.0

A security-hardening release. Conduit tightens the whole tool-trust boundary,
caps and filters what the gateway will fetch and sync, and adds accessibility and
UI polish.

Fixed

• The sidebar action bar stays put. It's pinned to the bottom of the server
  list and always visible instead of appearing only when you scroll to the end,
  and undetected clients collapse under a disclosure so the list stays short.

Security

• Hardened the anti-agentjacking scan. Tool results are normalized before
  scanning (lowercase, invisible/zero-width/bidi stripping, homoglyph and
  full-width folding) and base64-decoded payloads are scanned too, so injection
  text can't slip past with Unicode tricks or encoding. Nested structuredContent
  is scanned as well.
• Rug-pull detection covers more of the tool definition. Fingerprints now
  include outputSchema and annotations (version-tagged), so a server can't
  quietly change those behind an already-approved tool.
• Integrity pins fail closed. A corrupt or tampered pin baseline now raises a
  security event instead of silently resetting to trust-everything.
• Blocked RCE/SSRF from synced team config. Team sync drops stdio/command
  servers (remote code execution) and private-host URLs (SSRF); only public remote
  servers sync. The gateway also stops following HTTP redirects.
• Capped downstream responses. The gateway limits how much it reads from a
  downstream MCP server (16 MiB), so a hostile or runaway server can't exhaust
  memory.
• Validated catalog install specs. Registry-supplied package IDs with shell
  metacharacters or leading dashes are rejected, remote URLs must be http(s), and
  the registry fetch is size-capped.
• Teams/OAuth hardening. HTTP timeouts, a malformed-config guard, and token
  cleanup after a failed connect.

Accessibility

• Respects "reduce motion." When the OS prefers reduced motion, Conduit zeroes
  out spinners, pulses, dialog and tooltip zooms, and transitions.

Internal

• CI on every PR: frontend build, Rust library tests, and a gateway build
  check now run on pull requests across the project.
• macOS: newer secrets use the ACL-free SecItem keychain path, with a one-time
  migration of older entries (#26). The fuller DataProtection-keychain change is
  still in progress (it needs a code-signing approach that works for the gateway
  sidecar), so prompts behave as before for now.
• Removed leftover Vite/Tauri scaffold files and shipped a real favicon.

Thanks

• @bradhallett (#26) for the macOS keychain migration work.
