Anandan 1fde941803 perf: reduce startup and turn overhead (#932)
* perf(tui): disable duplicate composer cursor blink

* perf(tui): stop composer wakeups after idle

* refactor(tools): publish immutable registry snapshots

* perf(startup): defer optional tool discovery

* perf(provider): reuse compatible response sessions

* feat(provider): add native patch tool input

* fix(provider): recognize saved chat sessions

* perf(tui): render only on screen changes

* fix(runtime): address performance review findings

* fix(usage): expose cache efficiency details

* perf(agent): reduce redundant bounded-task turns

* fix: harden runtime review edge cases

* fix: address runtime review findings

* build: restore official Bubble Tea dependency

* fix(cli): redact MCP registration errors

* fix: harden turn session regressions

* fix: keep run tools and patch roots consistent

* fix: bind freeform patch writes to scoped roots

* test: keep patch fixtures out of worktree

* fix(tools): reject mixed-root freeform patches
