🎯 Changes

• intent maintainer setup discovered existing skills in findExistingSkills and then passed them to planAddSkills, which repeated projectPath lstatSync walks, uncached resolveProjectContext ancestor walks, package.json reads, and SKILL.md frontmatter reads across the batch.
• resolveProjectContext now caches findOwningPackageRoot results per IntentFsCache and uses a single statSync(path, { throwIfNoEntry: false }) probe in toSearchDir.
• projectPath, skillPath, recordPath, readRecord, and skillEntries accept a per-batch Set<string> of verified non-symlink paths so shared directory prefixes are checked once per operation.
• findExistingSkills, planSetupRecords, and planAddSkills share one IntentFsCache, verified path set, and parsed SKILL.md frontmatter across maintainer setup (planMaintainerSync also shares fsCache and verified paths across its skill loop), and findExistingSkills counts duplicate names in a Map instead of an $O(N^2)$ skills.some(...) scan.
• Command output, validation rules, and exit codes do not change.

Merging this PR will not alter performance

⚠️ 7 benchmarks spent significant time in system calls

System calls cannot be consistently instrumented, so they are not included in the measure, which understates the real cost. Please switch to the Walltime instrument to accurately measure system calls.

Measurement and system calls

• empty node process (baseline)
• registers the complete batch
• registers the complete batch
• intent validate prose-only skills
• scans a consumer workspace
• intent --help
• loads a direct dependency skill
