v0.6.0: complete all 12 local-model upgrades + raise maxIterations to 100

Upgrade candidates (all 12 done):
- #1 parallel read-only tool execution (runToolBatch, 4 loop sites)
- #2 configurable retry policy (maxRetries + exponential backoff via SDK)
- #3 script-aware token estimation (CJK/symbol/structure-aware heuristic)
- #4 head+tail output capping (truncate.ts), auto-applies to bash/git/etc
- #5 partial-history compaction (preserve recent tail, summarize older prefix)
- #6 dynamic max_tokens (resolveMaxTokens)
- #7 richer tool descriptions with "use when" guidance
- #8 MCP reconnect retry + /mcp reconnect command + session toolset refresh
- #9 context-window cache TTL (cachedAt timestamp, default 7 days)
- #10 edit_file similar-match suggestion on old_string miss (bounded Levenshtein)
- #11 git_status output head+tail (resolved via #4)
- #12 auto-accept now approves all mutating tools; auto-edit stays edit-only

Other:
- DEFAULT_MAX_ITERATIONS 50 -> 100 (local models issue one tool call per step)
- MaxIterationsError message guides resume + config override
- plus prior known-issues work (grep -e/--, session id sanitization, MCP content
  types, 12 hook events, plugin collisions, skill references, git ops expansion,
  configurable autoCompactThreshold, bashGuard, pathGuard, FilePanel, replay)
