log.py was bare print-to-stderr wrappers with no levels or attributable
context (issue #252). Add:
- Ordered severities (debug/info/warn/error) gated by
BOT_BOTTLE_LOG_LEVEL (default info). debug is silent by default;
error always surfaces (nothing sits above it), so the fatal die path
stays visible regardless of configured level.
- An optional `context` mapping on every wrapper, rendered as a
parseable ` [k=v ...]` suffix (keys sorted; whitespace/quoted values
quoted) so failures can be filtered and correlated.
Default output with no context is byte-identical to the original lines,
so the 100+ existing single-string call sites are unaffected. Wires the
supervise crash path (the example the issue names) to attach error_type
and crash_log context. Adds test_log.py (backward-compat, context
rendering, level gating, die surfacing).
Closes#252.
