81d00bd4e4 fix: prevent arrow markers from consuming node names starting with o/x
Fixes #2492

The flowchart parser was incorrectly consuming 'o' or 'x' characters from
node names when they appeared after arrows without spaces. For example,
`dev---ops` was parsed as "dev" → "ps" instead of "dev" → "ops".

Changes:
- Modified lexer patterns in flow.jison to distinguish between:
  - Intentional arrow markers (--o, --x) followed by whitespace or uppercase
  - Node names starting with 'o' or 'x' (lowercase continuation)
- Added 10 comprehensive tests to flow-arrows.spec.js covering:
  - Bug cases (dev---ops, dev---xerxes)
  - Backwards compatibility (A--oB, A --o B, etc.)
  - All arrow types (solid, thick, dotted)

The fix uses smart pattern matching:
- `--o ` (with space) → circle arrow marker
- `--oB` (uppercase) → circle arrow marker
- `--ops` (lowercase) → plain arrow, 'ops' is node name

All 24 new tests pass. All 293 existing edge tests pass.
