Improve troubleshoot analyzers: select/release inference, cache cross-diagnosis, richer reports and file discovery

[mouxinqq]

Motivation

• Improve accuracy and usability of the troubleshooting scripts by better correlating select/release events, inferring worker types for releases/tokens, surfacing cross-diagnostics for cache, and generating richer detail files for reports.

Description

• Enhance log_parser.match_select_release and related helpers to normalize worker URL keys, infer release/token worker types from nearby selects, use worker-FIFO matching, and produce richer per-worker/type summaries and profiles.
• Add counter last-state analysis and new regexes (select count / release worker count) in load.py, plus loosened diagnostics thresholds and additional diagnostics messages.
• Add cross-diagnosis logic for cache (session stickiness × hitRatio × fallback × evictions) and wire it into cache analyzer/reporting; split summary/detail outputs and add many detail files (cache_diagnosis, cache_*, load_counter_state, errors_topn, latency_diagnoses, etc.).
• Improve errors analyzer with IMPACT_RULES, classify_impact, URL extraction, and surface YAML-missing info; trace analyzer now invokes select/release checks and reports unmatched selects/releases.
• Health analyzer: include register events in timelines and compute detection latency metric; latency and load report formatters include metric notes and link to detail outputs.
• Fix chart.render_table alignment/separator generation.
• Improve troubleshoot.py log-file discovery (Path-based, fuzzy matching), add more detailed report assembly and save many detail files, and add user-friendly messages for missing files.
• Add helper functions and self-test case in log_parser.py to validate token-release inference behavior.

Testing

• Ran python3 scripts/log_parser.py self-test which includes select/release token-type inference checks and the added sample case, and the self-tests passed.
• Performed smoke runs of the troubleshoot orchestration against sample logs to verify that reports and new detail files (detail/...) are produced without exceptions.
• No unit test framework changes; all automated inline self-tests and script-level smoke checks completed successfully.
