Add holiday-gap detection via `exchange_calendars`

Integrate `exchange_calendars` lib to detect market holidays in
gap-checking logic via new `.ib.venues.has_holiday()` helper!

The `.ib.venues` impl deats,
- add  a new `has_holiday()` using `xcals.get_calendar()` and friends
  for sanity checking a venue's holiday closure-gaps.
  * final holiday detection-check is basically,
   `(cash_gap := (next_open - prev_close)) > period`
- include `time_step_s` param to `is_venue_closure()` for boundary
  tolerance checks.
  * let's us expand closure-time checks to include `+/-time_step_s`
    "off-by-one-`timeframe`-sample" edge case ranges.
- add real docstring to `has_weekend()`.

In `.ib.api` refine usage for ^ changes,
- move `is_venue_open()` call + tz-convert outside gap check
- use a walrus to capture `has_closure_gap` from `is_venue_closure()`
- add a `not has_closure_gap` condition to the
  mismatched-duration/short-frame warning block to avoid needless warns.
- keep duration-based "short-frame" log as `.error()` but toss in a bp
  so (somone can) umask to figure out wtf is going on..
  * we should **never** really hit this path unless there's a valid bug
    or data issue with IB/GFIS!
  * keep recursion path masked-out just leave a `breakpoint()` for now.

Also some logger updates,
- import `get_logger()` from top-level `piker.log` vs `.ib._util` which
  was always kinda wrong..
- change `NonShittyIB._logger` to use `__name__` vs literal.

+'''
+Programmatic debugging helper for `pdbp` REPL human-like
+interaction but built to allow `claude` to interact with 
+crashes and `tractor.pause()` breakpoints along side a human dev.
+
+Originally written by `clauded` during a backfiller inspection
+session with @goodboy trying to resolve duplicate/gappy ohlcv ts
+issues discovered while testing the new `nativedb` tsdb.
+
+Allows `claude` to run `pdb` commands and capture output in an "offline"
+manner but generating similar output as if it was iteracting with
+the debug REPL.
+
+The use of `pexpect` is heavily based on tractor's REPL UX test
+suite(s), namely various `tests/devx/test_debugger.py` patterns.
