Jamkris 086e44c964 fix(hooks): log fail-open breadcrumb on parse/read errors in metrics bridge
coderabbitai flagged: the two `catch` blocks in `readSessionCost`
silently swallowed every failure mode. A malformed `costs.jsonl`
row, a permission error opening the file, or any other unexpected
I/O failure would silently return zero cost — masking real
problems and feeding stale or zero numbers into
`ecc-context-monitor.js` (which then injects them as
`additionalContext` into the live model turn).

Fix two things, both fail-open-preserving:

1. **Inner JSON.parse catch** — count malformed lines and write
   one aggregated breadcrumb per call:

     [ecc-metrics-bridge] skipped N malformed line(s) in <path>

   Aggregating (rather than per-line) keeps a log-flooded
   `costs.jsonl` diagnosable without overwhelming stderr.

2. **Outer fs.readFileSync catch** — write a breadcrumb on real
   errors, but stay silent on `ENOENT`. The "no costs.jsonl yet"
   case is genuinely normal (no Stop event has fired this session)
   and producing noise on every PreToolUse before the first Stop
   would be reviewer-visible spam. All other error codes
   (`EACCES`, `EISDIR`, `EMFILE`, …) get:

     [ecc-metrics-bridge] failing open after <name> reading <path>: <msg>

In both cases the function still returns the zero-cost fallback
so the bridge never breaks tool execution — only the
diagnosability changes.

Two new regression tests in
`tests/hooks/ecc-metrics-bridge.test.js`:

  ✓ readSessionCost writes a stderr breadcrumb when malformed
    lines are skipped — feeds 4 rows (2 valid, 2 malformed),
    asserts the last valid row still wins AND captured stderr
    contains "skipped 2 malformed line(s)".

  ✓ readSessionCost stays silent when costs.jsonl does not exist
    (ENOENT) — uses a fresh tmp HOME with no metrics dir, asserts
    zero return AND empty stderr.

Test count: 16 → 18; `npm test` green; `yarn lint` clean.
