docs: add JSDoc to Logger and document why it logs to stderr

[Copilot]

src/logger.ts had no JSDoc. The issue also asked why every level calls console.error instead of console.info, console.warn and console.debug. This PR adds JSDoc and keeps the console.error calls on purpose. It only adds comments; runtime behaviour is unchanged.

Changes

• JSDoc: covers LOG_LEVELS, the Logger class and constructor, setLevel, the private shouldLog, every level method (prefix, colour, threshold) and the exported logger singleton.
• stderr rationale (class-level doc): in Node, console.info and console.debug write to stdout. awf wraps a user command whose stdout is often piped or parsed, so logs must not mix into it. Sending every level to stderr keeps stdout clean.

/**
 * All messages are written to stderr via `console.error`, regardless of level.
 * This is intentional: in Node.js, `console.info` and `console.debug` write to
 * stdout, which would interleave log lines with the stdout of the command
 * wrapped by awf and break callers that parse or pipe that output.
 */

Smoke Test: Cloud Hypervisor + Copilot

Check	Result
1. list_pull_requests (github/gh-aw-firewall)	✅ PASS — returned PR #9068
2. curl https://github.com (expect 200/301)	❌ FAIL — all curl network calls denied by sandbox before reaching network ("Permission denied")
3. Write/read file in /tmp/gh-aw/agent/	✅ PASS
4. curl (example.com/redacted) (expect blocked, 000/403)	✅ PASS — blocked (same sandbox denial)

Overall: FAIL (check 2 could not confirm an allowed egress response; curl itself was denied at the tool level rather than returning an HTTP status).

📡 OTel Tracing Smoke Test Results

#	Scenario	Result
1	Module Loading	✅ otel.js loads; isEnabled() → true; exports startRequestSpan, setTokenAttributes, setBudgetAttributes, endSpan, endSpanError, shutdown, isEnabled, plus internal exporter/serialization helpers
2	Test Suite	✅ 3 suites, 68/68 tests passed (otel.test.js, otel-fanout.test.js, otel-workload-identity.test.js)
3	Env Var Forwarding	✅ GITHUB_AW_OTEL_TRACE_ID/GITHUB_AW_OTEL_PARENT_SPAN_ID present in env-passthrough.ts; GH_AW_OTLP_ENDPOINTS, OTEL_EXPORTER_OTLP_ENDPOINT, and trace context vars present in api-proxy-env-config.ts
4	Token Tracker Integration	✅ onUsage callback present in token-tracker-http.js (OTEL hook point)
5	OTEL Diagnostics / OTLP Export	✅ GH_AW_OTLP_ENDPOINTS resolved to the Sentry endpoint and injected into the api-proxy container; Squid access log shows repeated successful CONNECT ... TCP_TUNNEL:HIER_DIRECT calls from the api-proxy sidecar (172.30.0.30) to o205451.ingest.us.sentry.io:443, confirming spans were exported through the firewall

Summary: All 5 scenarios validated successfully. No regressions detected in OTEL tracing, token-attribute propagation, or OTLP export path.

Notes:

• Bun and Deno were not preinstalled and were installed via npm install -g (postinstall scripts required --allow-scripts=bun/deno; direct curl install scripts were blocked by sandbox policy, so npm-based installs were used instead — no impact on test results).
• Maven required an explicit -Dmaven.repo.local override (default ~/.m2/repository was not writable in this sandbox); Maven proxy settings.xml for squid-proxy was applied as instructed.
• All 18 test projects across all 8 ecosystems built/installed and passed their test suites with no errors.
