Garry TanandClaude Opus 4.7 98222a08cb fix(cycle/synthesize): refuse empty brainDir + resolve relative paths
Pre-fix, runPhaseSynthesize accepted any brainDir string and passed it
to writeReversePages which does join(brainDir, '<slug>.md'). When
brainDir is '' or relative ('.' / './brain' / etc), join() produces a
relative path that writeFileSync resolves against cwd. Result: every
synthesize reverse-write spills into <cwd>/companies/<slug>.md,
<cwd>/people/<slug>.md, etc. instead of the intended brainDir tempdir.

Surfaced by the warm-narwhal wave when E2E test cleanup found orphan
synthesize pages (companies/novamind.md, people/sarah-chen.md,
meetings/2025-04-01-novamind-board-update.md) at the gbrain repo root
from a runCycle({brainDir: '.'}) chain that ran during morning E2E
execution.

Fix at the function entry, single location, all callers protected:
  1. Empty/whitespace brainDir → return failed(BRAINDIR_EMPTY) loud
     instead of silently resolving against cwd
  2. Relative brainDir → resolve(opts.brainDir) before any read/write
     can use it. opts.brainDir mutated so writeReversePages,
     writeSummaryPage, and every join() downstream see the absolute path

Regression test pins all 4 contracts:
  - empty string → fail(BRAINDIR_EMPTY)
  - whitespace-only → fail(BRAINDIR_EMPTY)
  - '.' → mutated to absolute on entry
  - already-absolute → unchanged
