Summary

Host release instruction (rant 2026-08-18T18:07:47): bump version to v0.2.49 to ship the two commits after v0.2.48:

• emrg: fix Windows installer DeleteFile code 5 — module-holder enumeration + isolated mode #844 — Windows installer DeleteFile code 5 fix: module-holder enumeration (Process.Modules detects DLL/.pyd lock holders — diagnostic proof: PID 9280 browser-harness child) + -I isolated mode (stop_all runs with python -I, no self-lock on install\lib) + taskkill /F /T tree kill + verify module-holder residual category + self-lock guard.
• emrg: unified rant tool — submit/list/update/cleanup actions + tolerant rants.jsonl parsing (rant 2026-08-18T16:42:52) #845 — unified rant tool: submit_rant extended to submit/list/update/cleanup 4 actions + tolerant rants.jsonl parsing (array rows → canonical dicts), fixing the format-drift/message-loss caused by hand-written curation scripts.
