mrcharles 11ec4cf4a3 fix: resolve discourse-mcp TS2345 build error and add env-var auth
The discourse-mcp was BLOCKED with a TypeScript TS2345 error caused by
the Dockerfile forcing SDK ^1.23.0 via `pnpm add`, while the upstream
code requires the lockfile's v1.17.3. Removed the override to use
`pnpm install --frozen-lockfile`.

The upstream server does not read environment variables directly — it
requires CLI args (--auth-pairs, --site) or a --profile JSON file. Added
a docker-entrypoint.sh that converts DISCOURSE_URL, DISCOURSE_API_KEY,
and DISCOURSE_API_USERNAME env vars into a profile JSON with auth_pairs
and site tethering.

Validated end-to-end: MCP handshake passes, site auto-tethers on startup,
live tool calls (discourse_search, discourse_filter_topics) return real
data from community.turnsys.com.

Updates STATUS.md and README.md to reflect discourse-mcp as production
ready. Adds JOURNAL.md entries for discourse-cli, discourse-mcp fix, and
protocol improvements.
