Commit Message

perf: throughput optimizations, coordinator pipelining, chaos UI improvements  (#61)

* feat: postgres soak test — 120 tables, writer tasks, fault injection, schema alters

* feat: postgres backlog drain, config lab UI, writer fixes

- Add postgres support to backlog drain benchmark (run_pg)
- Add Config Lab tab with A/B comparison runner and presets
- Add PATCH proxy endpoint to chaos UI backend
- Fix pg_writer_loop: reconnect on error, f64->numeric type mismatch
- Fix escape_like: escape underscore, convert glob * to SQL %
- Promote writer errors from debug to warn level
- Add df_base/pipeline fields to SoakSource

* clippy and formatting fixes

* perf: postgres CDC optimizations, chaos UI improvements

Source hot-path optimizations (profiler-guided):
- fast_uuid_v7: atomic counter replaces getrandom syscall (3.1% -> 0.2%)
- Remove #[instrument] from read_next_event/dispatch_event
- try_send with async fallback in send_event
- Arc<Vec<RelationColumn>> and Arc<str> qualified_name per relation
- Arc<PostgresTableSchema> in LoadedSchema cache
- Static PG_VERSION LazyLock, hand-written checkpoint JSON
- Pre-allocated batch vector in coordinator

Chaos UI:
- Config Lab tab with A/B comparison runner and presets
- Service refresh button (--no-deps --force-recreate)
- Dynamic port/URL link badges from docker port
- Grafana in-flight panel color thresholds (green=draining, orange=buffering)
- Wider services card layout

* chore: upgrade pgwire-replication to v0.3, fix clippy

- Update pgwire-replication to v0.3 (buffered WAL reads)
- Adapt Io error handling for Arc<io::Error> (use err.kind() not string match)
- Include ErrorKind in connect error details
- Fix clippy: range patterns, useless format!

* fix formatting

* perf: zero-copy tuples, counter cache, LSN cache - PG matches MySQL

Zero-copy tuple parsing:
- PgColumnValue::Text/Binary now hold Bytes slices (not String/Vec)
- parse_tuple_data uses Bytes::slice() instead of copy + from_utf8_lossy
- DML h... (continued)
