- Add shared browser error URL detection for Chrome, Edge, Brave, and Firefox-style about:error pages.
- Short-circuit read-only DOM and HTML commands with safe fallbacks when tabs are already on browser error pages.
- Fail navigation waits, DOM waits, polling, and URL watches with clearer error-page messages.
- Bump package and extension version to 0.9.8 and extend regression coverage for cross-browser error-page handling.
- Treat chrome error page script failures as transient during injection retries.
- Return safe fallback values for read-only DOM commands when tabs land on browser error pages.
- Improve URL watch handling by checking pending URLs and reporting last seen URL/status on timeout.
- Bump package and extension version to 0.9.6 and add regression coverage for error-page behavior.
- Domain-like --remote endpoints default to port 443; :443 is optional
- _normalize_endpoint strips :443 before storage in remotes.json
- _load_remotes normalises keys on load (backward compat migration)
- _remote_display_name omits :443 for domain endpoints
- _resolve_connect_endpoint adds :443 back for TCP connection

Security:
- serve.py: server now sends nonce challenge before accepting any command;
clients sign nonce + SHA256(canonical_payload) with Ed25519 key
- New --authorized-keys FILE option for serve; token auth still works as fallback
- Connection limit: BoundedSemaphore(64) in serve.py
- Secure file creation with os.open(..., 0o600) for token/key files
- New auth.py module: keygen, file key load/save, SSH agent protocol (pure Python),
sign/verify helpers compatible with both file keys and agent-held keys (YubiKey,
TPM, gpg-agent)
Features:
- YubiKey support via SSH agent protocol — no new runtime deps, just $SSH_AUTH_SOCK
- New `browser-cli auth` command group: keygen, trust, show, keys
- Global --key PATH flag (or BROWSER_CLI_KEY env) selects signing key;
pass "agent" or "agent:<selector>" to use SSH agent key
- BrowserCLI Python API gains key= parameter
Bug fixes (11 issues across two review passes):
- client.py: check response is not None before json.loads
- native_host.py: _read_exact_stream loop handles EINTR short reads; fix Windows
Listener leak on accept error
- __init__.py: open_wait / tabs_watch_url raise RuntimeError instead of silent None
- extension/tabs.ts: dedupe skips tabs without URL; tabsSort uses pendingUrl fallback
- extension/session.ts: removeListener before addListener prevents duplicate handlers
Breaking: TCP serve protocol now sends a challenge frame first (v0.9.0)
