The devserver now mirrors all honcho-routed console output to a log file (truncated each run) so it can be inspected after the fact — for example by AI agents reading the dev logs. ANSI color codes are stripped from the file copy while the interactive console keeps its coloring (the tee delegates isatty()). The path defaults to <repo>/.artifacts/dev.log and is configurable via the SENTRY_DEV_LOG_FILE environment variable. Both .artifacts/ and *.log are already gitignored.

Fixes getsentry/self-hosted#4379 Granian's watchfiles-based reloader watches the entire repo directory by default. The TeeStream introduced in #117486 writes all honcho output to .artifacts/dev.log inside the repo root, which triggered an infinite reload cycle: server logs →-> dev.log updated -> watchfiles detects change -> granian reloads -> repeat. Fix by passing reload_ignore_dirs=[".artifacts"] to Granian so watchfiles skips that directory. The option is surfaced through the existing options dict so it can be overridden via SENTRY_WEB_OPTIONS if needed. <!-- Describe your PR here. --> <!-- Sentry employees and contractors can delete or ignore the following. --> ### Legal Boilerplate Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Summary
The devserver now mirrors all honcho-routed console output to a log file (truncated each run) so it can be inspected after the fact — for example, by AI agents reading the local dev logs.
TeeStreaminsentry/runner/formatting.pywraps stdout: it writes to the console verbatim and writes an ANSI-stripped copy to the log file, flushing each write.TeeStream.isatty()delegates to the underlying console so honcho still colorizes terminal output; only the file copy is stripped.get_honcho_printer(...)gains an optionaloutputparameter; the devserver passes it aTeeStream.<repo>/.artifacts/dev.logand is configurable via theSENTRY_DEV_LOG_FILEenvironment variable. Both.artifacts/and*.logare already gitignored.This mirrors an approach already in use in the seer repo.
Notes
server.run()path are not tee'd, which is fine for the intended use case.
