fix: cwd fallback in findClaudeProjectDir — Claude Code encodes _ to - (v0.7.6)

Our encoder preserved underscores but Claude Code replaces ALL non-alphanum chars
with '-', so paths like I_CT encoded to I-CT, causing (0) sessions. Now falls back
to reading cwd from JSONL when encoded name doesn't match the fast path.
