* refactor(log): migrate logging to tracing-estuary pipeline
Swap flexi_logger + clash-verge-logger wiring for the tracing-estuary
crate: buffered file sink with explicit panic/exit drains, live level
switching, and tokio-trace/chrome-trace behind crate features.
AsyncLogger moves in-house (VecDeque ring); file format and rotation
stay unchanged.
* fix(log): reset sidecar writer in place and re-pin service-ipc v2.6.7
Rebuilding the sidecar FileLogWriter on config changes leaked flexi's
unstoppable flusher thread plus an fd each time; the writer is now flushed
and reset in place, matching what the service crate does.
get_clash_logs_by_service drops the CompactString conversion layer now that
service-ipc v2.6.7 returns plain Vec<String>, and AsyncLogger is renamed
LogRing to match.
* refactor(log): span-based observability and log noise cleanup
Instrument spans carry the structure flat lines never could: the core-start
spine (mode, readiness/owner generations, pid, config file), proxy apply and
clear routes with guard generations, service IPC sessions with refusal codes
and outcomes, profile-switch terminal outcomes, subscription fetch strategies,
core upgrades with per-proxy version probes, backup flows, timer tasks, config
generation uids, and the startup setup flow; running-mode changes emit one
guarded transition event each.
~90 hand-written noise lines are gone or demoted (entry+success pairs, polled
getter echoes, phase brackets, window sub-steps, platform install chatter);
errors keep their anyhow chain, operation name, and item id, and swallowed
retry results surface per attempt.
Drive the production home traffic graph through embedded WebDriver in an
isolated optimized measurement build. Record attributed WebContent and main
process CPU/RSS distributions across foreground, hidden and restored phases.
Keep replay, raw reports, independent-run comparison, cleanup checks and
focused validation available through project commands. Normal release builds
exclude the automation service and measurement entry points.
This prevents the runtime from spawning an excessive number of threads on
high-end CPUs, reducing memory footprint and context switching.
Introduces a dynamic cap for worker threads (max 16) and scales
blocking threads proportionally. Includes thread naming for diagnostics.
