[BUG] Preserve parser failure state when retry setup fails #42

Type

Bug

Problem / Value

An explicit indexing retry clears the remembered parser failure before replacement services are ready. If rebuilding those services fails, later automatic initialization no longer sees the original parser-failure guard.

Context

Deferred re-review finding 🟢12 from PR #34: #34, which addresses #23. Source reviewed: 8c38f1c.

The failure flag is cleared before the asynchronous recreation step is awaited. Impact is limited because a separate services-stopped flag remains set; this issue does not claim that automatic indexing definitely restarts today.

Reproduction

Proposed regression test: cause a parser failure, explicitly retry, make service recreation reject, then exercise subsequent automatic initialization and another explicit retry. This failure injection was not run during filing.

Acceptance criteria

• Keep or restore the parser-failure guard if service recreation fails.
• Clear it only as part of a successful, explicit recovery.
• Keep failure status and retry guidance accurate after failed setup.
• Test failed recreation, successful retry, and automatic initialization after failure.

Constraints/Preferences

Preserve the separate services-stopped protection. Do not combine this follow-up with the already-fixed retry double-rebuild finding 2.
