feat(cli): add ingest LLM rate-limit governor with paced retries (#261)

Browse source 
* feat(cli): add ingest rate limit governor

* feat(cli): wire ingest rate-limit config

* feat(cli): report provider rate-limit signals

* feat(cli): show ingest rate-limit waits

* fix(cli): complete rate-limit event coverage

* fix(cli): abort ingest provider calls cleanly

* fix(cli): propagate ingest cancellation

* fix(cli): reject pre-aborted ingest rate-limit waits

* fix(cli): honor Claude rate-limit reset waits

* fix(cli): retry thrown Codex rate-limit failures

* fix(cli): type Claude rate-limit result details

* fix(cli): emit ingest rate-limit countdowns from rejected signals

* fix(cli): report ai sdk rate-limit header utilization

* fix(cli): gate LLM rate-limit retries on the governor budget

The AI SDK and Codex runtimes retried 429 / opaque rate-limit failures up
to 6-7 times with no backoff when constructed without a RateLimitGovernor
(scan, memory, setup) or with pacing disabled, ignoring Retry-After and
worsening the limit. The outer retry loop only cooperates with the
governor's pause, so without active pacing there is no backoff to apply.

Route the retry bound through a single source: RateLimitGovernor
.maxRetryAttempts(), which returns retry.maxAttempts when enabled and 1
(no outer retry) when absent or disabled. All three runtimes (ai-sdk,
codex, claude-code) now use it, so ingest.rateLimit.retry.maxAttempts
genuinely controls attempts and the hard-coded 6 (plus Codex's off-by-one
extra attempt) is gone. Backend-native retry (e.g. the AI SDK's maxRetries)
still handles transient 429s.

Also correct the ktx.yaml docs for maxWaitMs (caps each wait, not the whole
run) and maxAttempts, and sync uv.lock ktx-sl/ktx-daemon to 0.9.0.
