ENG-1270: convert from log to tracing (#3026)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Replaces fern/log with tracing + tracing-subscriber (with
EnvFilter/JSON/file rotation) and OTEL tracing appender, updating all
modules to use tracing macros.
> 
> - **Logging overhaul (CLI)**:
> - Replace `fern`/`log` with `tracing` + `tracing-subscriber`
(EnvFilter, JSON/text formats, optional modern/legacy formatter).
> - Implement OTEL export via `opentelemetry-appender-tracing`; add
batch log processor and resource labels.
> - Add date-based file writer compatible with previous naming; cleanup
old logs; session/machine IDs in events.
> - Introduce legacy format layer to match prior output; opt-in modern
formatting via env var.
> - **Codewide changes**:
> - Swap `log::{...}` macros for `tracing::{...}` across CLI, framework,
infra, and MCP modules; adjust some log levels (e.g., HTTP metrics to
trace).
> - **Dependencies**:
>   - Remove `fern`, `log`, and `opentelemetry-appender-log`.
> - Add `tracing-subscriber`, `tracing-serde`, and
`opentelemetry-appender-tracing`; update lockfile accordingly.
