* fix(agent-context): recurse for nested plans in Python mtime fallback
The Python port's mtime fallback discovered plans with a one-level
specs/*/plan.md glob, so a scoped layout created via
SPECIFY_FEATURE_DIRECTORY (specs/<scope>/<feature>/plan.md) was missed when
feature.json is absent — the fallback returned no plan and the managed
context section omitted the 'at <plan>' line. The bash and PowerShell twins
were already fixed to recurse (#3024); the Python twin was left behind.
Switch to specs.rglob('plan.md') with the same symlink-safe containment check
the bash twin uses (resolve each candidate and confirm it stays within the
project root before ranking by mtime), so a plan reached through a specs/
symlink pointing outside the project is not selected.
Adds parity regression tests (vs bash and vs PowerShell) covering a nested
specs/<scope>/<feature>/plan.md; both fail on the pre-fix one-level glob.
Fixes#3733
* test(agent-context): cover symlink containment in the mtime fallback
The recursive fallback resolves each candidate before the relative_to()
containment check, but nothing exercised that path. Add a parity test for a
plan reachable only through a specs/ symlink pointing outside the project:
relative_to() is lexical and would accept it, emitting an in-project-looking
path for an out-of-project file. Both the bash twin and the Python port skip
it, so the "at <plan>" line is omitted.
Also correct the module docstring, which still described the fallback as
scanning specs/*/plan.md one level deep.

* fix: use missing_ok for temp file cleanup to avoid masking errors
When the extension config omits context_markers (or sets them blank),
relying on the built-in defaults, the Bash port aborted with "malformed
config parser output" and never updated the context file, while the
Python (`or DEFAULT_*`) and PowerShell (default-initialized) ports handled
it correctly.
The config parser prints three lines (context_files JSON, marker_start,
marker_end), captured via `_raw_opts="$(...)"`. Command substitution strips
trailing newlines, so blank marker lines collapse the output to fewer than
three, tripping the `(( ${#_opts_lines[@]} < 3 ))` guard and making the
DEFAULT_START/END substitution unreachable — the exact case it was written
for.
Require only the context_files line and default the marker lines to empty
(`${_opts_lines[1]:-}` / `${_opts_lines[2]:-}`) so the existing
DEFAULT_START/END fallback fills them in. Add a parity regression test with
blank markers (it fails on the old guard and passes with the fix).

The Python port of update-agent-context reintroduced a one-level plan
scan (specs/*/plan.md) in its mtime fallback, while the Bash and
PowerShell ports search recursively (specs/**/plan.md) per the fix for
issue #3024. The three ports were therefore not in parity: for nested
scoped layouts such as specs/<scope>/<feature>/plan.md, the Python port
found no plan and omitted the plan link from the managed context section.
Switch the fallback to `(root / "specs").rglob("plan.md")` and update the
module docstring to match the documented recursive-discovery contract.
Add a parity regression test covering the nested layout (it fails on the
one-level glob and passes with the recursive scan).

* feat(extensions): port update-agent-context to Python
Ports the agent-context extension updater to a single Python script,
per #3281 and the check-prerequisites PoC pattern from #3302. The bash
version already ran its core logic through embedded Python heredocs, so
the port lifts that logic into a standalone script. Parity tests run
bash and Python side by side and compare output and resulting
context-file bytes.
