* fix: restore origin-scoped --headers persistence across commands
In the v0.20 Rust rewrite, headers passed via --headers on open were
only applied to that single navigation via Network.setExtraHTTPHeaders,
which did not persist them for subsequent commands. In v0.19
(Playwright-based), these headers persisted for all subsequent
same-origin requests.
This restores the v0.19 behavior using CDP Fetch interception:
- A background task processes Fetch.requestPaused events in real-time,
injecting origin-scoped headers into matching requests and continuing
non-matching requests unmodified. This avoids the deadlock that occurs
when Fetch interception pauses requests during Page.navigate or
Runtime.evaluate (which block waiting for completion).
- The same background task also handles domain filtering and route
interception, replacing the previous drain-between-commands approach
that couldn't process events during navigation or script evaluation.
Fixes:
- --headers persist for same-origin navigations without re-passing flag
- --headers persist for in-page fetch/XHR to the same origin
- --headers do not leak to cross-origin navigations or sub-resources
- `set headers` (global) is unaffected and stacks with --headers
- Domain filter Fetch interception no longer deadlocks during navigation
