fix(doctor): keep the session recovery marker out of tracked .sageox/

[aditeya08varma]

Fixes #1062

What broke

• .sageox/.session-recovery.json holds a per-machine absolute workspace_path, and it was not in the managed .sageox/.gitignore.
• It is worse than the report: a plain ox doctor (no --fix) stages the file itself. GetSageoxFilesToCommit matches .sageox/*.json, and ForceAddSageoxFiles runs git add -f, which overrides every ignore rule. So a gitignore entry alone, or a .git/info/exclude entry, does not stop it. That is why the file in the report sat staged even with a local exclude.

What this PR ships

• Adds .session-recovery.json to sageoxGitignoreContent and requiredGitignoreEntries, next to the .needs-doctor* markers. Existing repos pick it up on their next ox doctor, the same way agent_tasks/ was rolled out.
• GetSageoxFilesToCommit skips any match whose name is in requiredGitignoreEntries, so ox never force-stages a file its own gitignore ignores. Today this only changes behavior for this marker.
• The "Repo state" check no longer counts a file listed in requiredGitignoreEntries as config to commit. If one is already in the index (the case in the report, where the marker was staged before this fix), doctor warns and says to unstage it with git rm --cached <path> instead of "Run 'git commit' to persist config". It only gives the advice and does not touch the index, matching how doctor handles other index removals.

	Before	After
git check-ignore .sageox/.session-recovery.json	not ignored	ignored
after plain ox doctor	A .sageox/.session-recovery.json + "run git commit" nudge	not staged, no nudge
marker already staged before the fix	"Run 'git commit' to persist config"	warning: unstage with git rm --cached .sageox/.session-recovery.json

Why ignore it instead of moving it

Moving the file into agent_instances/ (option 1 in the issue) would leave existing copies at the current path, and doctor would keep force-staging them. Nothing reads or deletes the marker today, so they would never be cleaned up. Ignoring it plus the staging skip covers new and existing files, with no storage path change.

Testing

• TestSessionRecoveryMarker_NotStagedOrNudgedByDoctor: on a fresh repo, a plain ox doctor must not stage the marker. Before the fix it fails with A .sageox/.session-recovery.json.
• TestSessionRecoveryMarker_IgnoredAfterDoctorUpgradesOldGitignore: a repo with the old gitignore gets the new rule.
• With only the staging skip removed, the first test still fails. That proves the gitignore entry alone is not enough.
• TestSessionRecoveryMarker_AlreadyStagedIsFlaggedNotNudgedToCommit: a marker already in the index must get the unstage advice. Before the fix it fails with "Run 'git commit' to persist config".
• The related gitignore and staging tests, -race -count=3, and make test pass.

Notes

• Clones that already committed the file still need one git rm --cached .sageox/.session-recovery.json. Doctor shows that advice when the file is staged or modified. A committed copy that has not changed since does not show up in git status, so doctor does not flag it.
• .sageox/distill-state.json looks like the same kind of per-machine file. I left it alone because I am not sure it is meant to be local.
