Adds plugins/web/perplexity — a keyed-only WebSearchProvider over httpx:
- search: POST https://api.perplexity.ai/search (documented Search API),
search_context_size=low so `snippet` stays description-sized;
results[].snippet -> description, max_results capped at the API's 20.
- extract: POST /sdk/content/snippets — the query-relevant page-excerpt
route behind `pplx content snippets` (the CLI's `content fetch` is
deprecated upstream). web_extract has no query, so the URLs' path words
serve as the relevance query; per-URL `error` entries survive a 200.
- Wired into the same touchpoints as the other keyed vendors: legacy
backend set + credential ladder + availability probe (web_tools),
registry preference walk, OPTIONAL_ENV_VARS, `hermes config`/status/
dump key lists, nous_subscription direct-credential detection, setup
summary, test conftests, docs.
Not a keyless-ring member (Perplexity has no anonymous tier). Related
closed PRs #9192 / #23981 / #45225 predate the plugin ABC.
- new hermes_cli/status_auth.py: _render_api_keys / _render_auth_providers /
_render_nous_gateway / _render_apikey_providers + their data tables and the
OAuth/timestamp helpers; origin helpers imported lazily so status monkeypatches hold
- status.redact_key was a verbatim copy of hermes_cli.config.redact_key -> imported
- sessions/cron/deep/footer renderers compacted; 624 -> 372 lines (base 639)
Parity: r2m_status_golden.py 33 fixtures byte-identical vs base; real
`hermes status`, `status --deep`, `status --help` byte-identical after normalizing
the per-run temp HERMES_HOME path; test_status*/test_estop/test_jobs_json_utf8_bom green.
