v0.46.0: security, Docker UID/GID, model discovery, i18n, cancel fix

* fix: decode HTML entities before markdown processing + zh/zh-Hant translations (#239)

Adds decode() helper in renderMd() to fix double-escaping of HTML entities
from LLM output (e.g. <code> becoming <code> instead
of rendering). XSS-safe: decode runs before esc(), only 5 entity patterns.

Also adds 40+ missing zh (Simplified Chinese) translation keys and a new
zh-Hant (Traditional Chinese) locale with 163 keys.

Fix applied: removed duplicate settings_label_notifications key in both
zh and zh-Hant locales.

Fixes #240

* fix: restore custom model list discovery with config api key (#238)

get_available_models() now reads api_key from config.yaml before env vars:
  1. model.api_key
  2. providers.<active>.api_key / providers.custom.api_key
  3. env var fallbacks (HERMES_API_KEY, OPENAI_API_KEY, etc.)

Also adds OpenAI/Python User-Agent header and a regression test covering
authenticated /v1/models discovery.

Fixes users with LM Studio / Ollama custom endpoints configured in
config.yaml whose model picker silently collapsed to the default model.

* feat: Docker UID/GID matching to avoid root-owned .hermes files (#237)

Adds docker_init.bash with hermeswebuitoo/hermeswebui user pattern so
container files match the host user UID/GID. Prevents .hermes volume
mounts from being owned by root when using a non-root host user.

Configure via WANTED_UID and WANTED_GID env vars (default 1000/1000).
Readme updated with setup instructions.

Fix applied: removed duplicate WANTED_GID=1000 line in docker-compose.yml
that was overriding the ${GID:-1000} variable expansion.

* security: redact credentials from API responses and fix credential file permissions (#243)

Adds response-layer credential redaction to three endpoints:
  - GET /api/session — messages[], tool_calls[], and title
  - GET /api/session/export — download also redacted
  - SSE done event — session payload in stream
  - GET /api/memory — MEMORY.md and USER.md content

Adds api/startup.py with fix_credential_permissions() at server startup.
Adds 13 tests in tests/test_security_redaction.py.

Merged with #237 container detection changes in server.py.

* fix: cancel button now interrupts agent and cleans up UI state (#244)

Wires agent.interrupt() into cancel_stream() so the backend actually
stops tool execution when the user clicks Cancel, rather than only
stopping the SSE stream while the agent keeps running.

Changes:
  - api/config.py: adds AGENT_INSTANCES dict (stream_id -> AIAgent)
  - api/streaming.py: stores agent in AGENT_INSTANCES after creation,
    checks CANCEL_FLAGS immediately after store (race condition fix),
    calls agent.interrupt() in cancel_stream(), cleans up in finally block
  - static/boot.js: removes stale setStatus(cancelling) call
  - static/messages.js: setBusy(false)/setStatus('') unconditionally on cancel

Race condition fix: after storing agent in AGENT_INSTANCES, immediately
checks if CANCEL_FLAGS[stream_id] is already set (cancel arrived during
agent init) and interrupts before starting. Check is inside the same
STREAMS_LOCK acquisition, making it atomic.

New test file: tests/test_cancel_interrupt.py with 6 unit tests.

* docs: v0.46.0 release notes, bump version, update test counts
