fix(engine): give fleet-run-manifest a dedicated per-repo worktree default

The bare-string repo branch in normalizeRepoList defaulted maxConcurrentWorktrees
from DEFAULT_FLEET_RUN_MANIFEST.totalConcurrentWorktrees (a fleet-wide total),
while the object-form branch defaulted from a hardcoded literal 1. The two agree
only because the fleet-wide total default is also 1 today; changing it would
silently move the per-repo default for bare-string entries.

Introduce DEFAULT_FLEET_RUN_MANIFEST_REPO_MAX_CONCURRENT_WORKTREES as the single
source of truth for the per-repo default and use it in both branches.

Closes #9324

Review summary
This PR extracts the per-repo worktree default into a dedicated `DEFAULT_FLEET_RUN_MANIFEST_REPO_MAX_CONCURRENT_WORKTREES` constant and uses it consistently for both the bare-string and object-form repo entry branches in `normalizeRepoList`, decoupling it from the fleet-wide `totalConcurrentWorktrees` default. The change is correct and narrowly scoped: both defaults are currently `1`, so behavior is unchanged today, but the coupling that previously existed (bare-string branch silently inheriting the fleet-wide total) is now removed. The new test explicitly drives a non-default fleet-wide total through the parser to prove the per-repo defaults don't inherit it, which is a real regression test for the described bug, not a fabricated scenario.

Nits — 3 non-blocking

• The doc comment on the new constant (fleet-run-manifest.ts:48-51) is verbose for a single-line primitive constant; could be trimmed to state just the invariant without repeating the fleet-wide/per-repo distinction already covered in the type-level docs above it.
• index.ts is growing into a very large barrel file (~580 lines); unrelated to this PR but worth flagging as an ongoing maintainability concern for barrel-export files in this package.
• Consider whether `MAX_MANIFEST_REPOS` or other manifest-wide constants should eventually move to a single `constants.ts` alongside this new export, though not required for this PR.

Addressed
The PR adds a dedicated DEFAULT_FLEET_RUN_MANIFEST_REPO_MAX_CONCURRENT_WORKTREES constant, uses it in both the bare-string and object-form branches of normalizeRepoList, leaves DEFAULT_FLEET_RUN_MANIFEST.totalConcurrentWorktrees untouched, and adds a test that varies the fleet-wide total via manifest input while asserting bare-string and object-form entries still fall back to the dedicated constan
