- New GET /api/connect quick-connect endpoint for external integrations
- Ad-hoc mode (poweruser+): hostname/protocol/port params, redirects to client
- Address book mode (operator+): scope/folder/entry params, credentials from Vault
- Unauthenticated users redirected through SSO login and back automatically
- OIDC deep-link support: login handler accepts ?next= param, stores as cookie,
callback redirects there instead of /addressbook.html after authentication
- New docs/netbox.md integration guide: Custom Fields, Custom Links with
console_enabled/console_mode gating, webhook-driven address book sync
- Updated docs/api.md with GET /api/connect endpoint documentation
- Updated screenshots/screenshots.md with descriptions for all screenshots
- Bump version to 0.3.1

russh 0.54.1 fixes CVE-2025-54804 (integer overflow panic in channel
window adjust). Adapts tunnel.rs to the new API: AuthResult enum
instead of bool, native async trait instead of #[async_trait], and
keys module re-exported from russh directly.

Multi-hop SSH tunnel chains allow routing any session type through
multiple bastion hosts. VNC is now a first-class session type.
Web browser sessions can tunnel through jump hosts with automatic
URL rewriting.

- Patch guacd with Kerberos NLA support (002-kerberos-nla.patch),
based on upstream GUACAMOLE-2057 PR #581, adapted for FreeRDP 3.x
- Add per-entry auth_pkg, kdc_url, and prompt_credentials settings
to the address book (configurable in admin UI)
- Frontend credential prompt for entries without stored credentials
or with prompt_credentials enabled (never stored, session-only)
- Wire auth-pkg, kdc-url, kerberos-cache params through rustguac
to the guacd RDP handshake
- Comprehensive Kerberos NLA docs: krb5.conf setup, KDC discovery
options, FQDN requirements, troubleshooting guide

SSO button is now the primary action on the login page — larger,
bolder, and displayed first. API key login is hidden behind a
chevron toggle for admin use. Falls back to showing the API key
form directly when OIDC is not configured.

User API tokens allow OIDC users to authenticate via bearer token for
automation and scripting. Powerusers and admins can create their own
tokens; admins can create tokens for operators. Tokens use SHA-256
hashing, optional max_role caps, optional expiry, and full audit
logging of create/revoke operations with client IPs.
- DB schema: user_api_tokens and token_audit_log tables
- Auth middleware: validates user tokens as fallback after admin keys
- API: 7 new endpoints (self-service + admin token management)
- UI: tokens.html (self-service) + admin.html token/audit sections
- Nav: Tokens link added to all pages (visible for operator+)
- Docs: API reference, security model, roles/access control updated
- Background cleanup: expired tokens + 90-day audit log retention

libFuzzer+ASan+UBSan harness for guac_parser_append() — the C state
machine that parses all Guacamole wire-format input in guacd. 3.2M
iterations found no memory corruption; one non-exploitable signed
integer overflow (UBSan) in the length prefix accumulator noted in
FINDINGS.md.
Also adds FINDINGS.md for the Rust protocol parser fuzzer documenting
the UTF-8 boundary panic fix from v0.1.3.

Add cargo-fuzz targets for the Guacamole protocol parser:
- protocol_parse: single instruction parsing
- protocol_stream: streaming parser with chunked input
Fix panic in Instruction::parse when a length prefix splits a multi-byte
UTF-8 character (found by fuzzer within seconds). Now returns
ParseError::Truncated instead of panicking on invalid char boundary.
Run with: cargo +nightly fuzz run protocol_parse
cargo +nightly fuzz run protocol_stream

- Vault TLS: replace hardcoded danger_accept_invalid_certs(true) with
configurable tls_skip_verify option (default: false)
- Share tokens: use constant-time SHA-256 hash comparison to prevent
timing side-channel attacks
- OIDC pending states: add 10-minute TTL, evict stale entries on each
login to prevent unbounded HashMap growth
- Recording path traversal: add canonical path validation as defense-
in-depth alongside existing string checks
- Frontend XSS: escape all user-controlled data (filenames, paths) in
innerHTML via escapeHtml/escapeAttr in client.html and recordings.html
