The MEOS error handler threw a DuckDB exception from inside a C callback, unwinding through MEOS C stack frames (undefined behaviour leaving MEOS error/lwgeom/GEOS state inconsistent, so a later call crashed non-deterministically). It now siglongjmp()s to a thread-local landing pad and throws from pure C++; the scalar choke point and a new BoundCastData cast trampoline run MEOS work inside that pad, and casts take the same serialization mutex scalars use since MEOS global state (pg-derived timezone, legacy GEOS) is not thread-safe. Valid input is unaffected; invalid input still raises a clean DuckDB error. Stacked on #134 (fix/bump-meos-pin) because clean main pins a pre-MeosType MEOS that no longer compiles; base retargets to main once #134 lands. Introduces zero regression versus #134; a separate pre-existing, environment-specific tgeompoint.test localtime crash on the #134 base is unrelated and out of scope.

`meosType` (lower-case) is the **pre-consolidation** MEOS type name;
`MeosType` (upper-case) is the **post-consolidation** target that the
upstream rename sweep has not yet reached.  The current vcpkg pin
(`vcpkg_ports/meos/portfile.cmake` REF f11b7443ee98…) is still
pre-consolidation: `meos/include/temporal/meos_catalog.h` line 121
declares the typedef as `} meosType;` and every MEOS API uses the
lower-case spelling.  MobilityDuck's source code consistently uses
`meosType` to match — `grep -rn '\bMeosType\b' src/` finds the name
only on the alias line and its comment, nowhere else.

c8cad6d added `using meosType = MeosType;` as a forward-looking
bridge for the eventual consolidation bump.  That bridge points at
`MeosType`, which the current pin does NOT yet expose, so it
breaks every PR's Linux arm64 build with:

  /duckdb_build_dir/src/include/tydef.hpp:18:18:
    error: ‘MeosType’ does not name a type; did you mean ‘meosType’?

The fix is to drop the premature alias and replace the misleading
comment with one that documents the pre/post-consolidation distinction
and the resume path for the next pin bump — at that point a reviewer
can either restore the bridge (this time it'll be valid because
`MeosType` will exist) or sweep the MobilityDuck source from
`meosType` to `MeosType` in a single PR.

Reviewer's quickstart — ~10 minutes

What this PR does in one sentence: replaces MobilityDuck's MEOS error handler (which threw a DuckDB exception from inside a C callback — undefined behaviour unwinding through MEOS C frames, leaving MEOS / lwgeom / GEOS state inconsistent and causing non-deterministic crashes) with a siglongjmp() to a thread-local landing pad, then throws from pure C++.

Why this is important: it's a class of latent bugs that the user's MobilityDB-wide #1091 work also addresses, but from the embedder side. After this PR, the embedder side never returns control into MEOS after a fired error.

Files to read (priority order):

  1. src/include/mobilityduck/meos_error_guard.hpp (new) — the MEOS_ERROR_GUARD { ... } macro and the TLS landing pad.
  2. src/include/mobilityduck/meos_guarded_cast.hpp (new) — the BoundCastData cast trampoline that runs cast functions inside the guard.
  3. src/mobilityduck_extension.cpp — registers the new error handler; takes the serialization mutex around casts (MEOS global state — pg-derived timezone, legacy GEOS — is not thread-safe).
  4. src/geo/*.cpp + src/temporal/*.cpp — each scalar choke point wrapped in MEOS_ERROR_GUARD. Pattern is uniform; spot-check 2 files to confirm.

Verification:

# Reproduces the historic SIGSEGV pattern before this PR
duckdb -c "LOAD mobilityduck; SELECT geog_in('not valid wkt');"
# Before: process kill. After: clean DuckDB exception.

Cross-link: depends on #161 for the Linux arm64 build. Once #161 lands, this rebuilds clean.

Why it's safe to merge: valid-input paths are unaffected (the guard only fires on error). Invalid-input paths now raise a clean DuckDB exception instead of UB. The TLS landing pad is the standard pattern (PROJ / libgeos / Python all use setjmp/longjmp to escape C error contexts).

Potential overlap with #158: both PRs install a custom MEOS error handler. The two strategies are alternatives — #158's handler throws an InvalidInputException (simpler but UB through C frames per this PR's analysis); this PR's handler siglongjmp()s first then throws (safer). If both merge, this PR's handler wins (it's installed second in LoadInternal); the user may want to keep #158's simpler version and only rope in the parts of this PR that touch the casts. Worth a maintainer call.

declares the typedef as `} meosType;` and every MEOS API uses the
lower-case spelling.  MobilityDuck's source code consistently uses
`meosType` to match — `grep -rn '\bMeosType\b' src/` finds the name
only on the alias line and its comment, nowhere else.

c8cad6d added `using meosType = MeosType;` as a forward-looking
bridge for the eventual consolidation bump.  That bridge points at
`MeosType`, which the current pin does NOT yet expose, so it
breaks every PR's Linux arm64 build with:

  /duckdb_build_dir/src/include/tydef.hpp:18:18:
    error: ‘MeosType’ does not name a type; did you mean ‘meosType’?

The fix is to drop the premature alias and replace the misleading
comment with one that documents the pre/post-consolidation distinction
and the resume path for the next pin bump — at that point a reviewer
can either restore the bridge (this time it'll be valid because
`MeosType` will exist) or sweep the MobilityDuck source from
`meosType` to `MeosType` in a single PR.

…t_functions.cpp

PR MobilityDB#149's source-rename cherry-picks (2473d38 temptype rename −1087 lines,
99d6711 drop restr/at_value, 4d125ff 2-arg API) were based on an earlier
parity state and clobbered the parity-final-batch / th3index function
definitions (Temporal_time_bins, Tnumber_*_boxes, Acovers/Ecovers/Tcovers
family, Bearing_*, Tspatial_transform_pipeline) that the registration
tables in temporal.cpp / tgeogpoint.cpp / *_ops.cpp still reference —
producing 'undefined reference' link errors.

Restore both files from feat/parity-th3index (the complete superset that
PR MobilityDB#178 carries) and re-apply only the temptype_continuous ->
temptype_supports_linear rename via sed, preserving every parity
definition while keeping the new-MEOS symbol name.
Adds the SIZEOF_LONG_LONG emission to the rendered pg_config.h so the
DuckDB-Wasm (wasm32-emscripten / ILP32) build of MEOS no longer fails the
pg_bitutils integer-width check.
Scalar and cast bodies run MEOS on DuckDB TaskScheduler worker threads, which
need a per-thread meos_initialize(); a thread-local guard in the scalar exec
wrapper and a cast trampoline (RegisterMeosCastFunction) cover every entry
point, so timestamp formatting no longer dereferences a NULL session_timezone.
Per-type DuckDB callbacks and blob helpers have internal linkage and a single
canonical blob round-trip (TemporalToBlob / BlobToTemporal) declared once in
temporal/temporal_blob.hpp, so each function-pointer registration binds to its
own body.
…rames

MEOS reports errors through a C callback; throwing a DuckDB exception straight
out of it unwinds through MEOS C frames, leaving the thread-local error buffer
and GEOS context half-updated so the next MEOS call segfaults. Install a
sigsetjmp landing pad around every scalar and cast body in the shared exec
wrappers; the handler siglongjmp()s back to it and the exception is thrown from
pure C++ frames.
