Alan Wizemann 03bf5262bb feat(templates): install-time {{PROJECT_DIR}} substitution in cron prompts
Hermes doesn't set a working directory when firing cron jobs, so any
relative path in a template's cron prompt (`.scarf/config.json`,
`status-log.md`, etc.) resolves against whatever dir Hermes happens
to be in — NOT the installed project. Practical effect: site-status-
checker's cron job fires, agent runs with relative paths, finds
nothing to read, silently bails. User sees "Run now" complete with
zero output and nothing updated on disk.

Fix: the installer now substitutes template-author placeholders in
cron prompts at install time, before calling `hermes cron create`.
The registered cron job carries a fully-qualified, CWD-independent
prompt.

Supported tokens (deliberately few — each is part of the template
format contract from now on):

- `{{PROJECT_DIR}}` — absolute path of the installed project dir.
  The one that was motivating this fix; required for any cron prompt
  that reads or writes project files.
- `{{TEMPLATE_ID}}` — the `owner/name` from the manifest, for
  templates that want to tag delivery payloads or log lines.
- `{{TEMPLATE_SLUG}}` — the sanitised slug used by the installer for
  dir name + skills namespace, for templates that want to reference
  their skills install path.

Implemented as a static `ProjectTemplateInstaller.substituteCronTokens`
so it's testable as a pure function. Unsupported placeholders pass
through verbatim — template authors notice in testing that their
token didn't get replaced and either use a supported one or file
a request.

Site Status Checker v1.1.0 updated to use the tokens:
- cron/jobs.json prompt now opens with "Run the site status check
  for the Scarf project at {{PROJECT_DIR}}" and references
  {{PROJECT_DIR}}/.scarf/config.json, {{PROJECT_DIR}}/status-log.md,
  and {{PROJECT_DIR}}/.scarf/dashboard.json explicitly.
- AGENTS.md gains a note explaining that the cron-registered prompt
  carries absolute paths (installer substitutes at install time),
  while interactive-chat agents can keep using relative paths.
- bundle rebuilt, catalog regenerated.

templates/CONTRIBUTING.md documents the three supported tokens under
the cron/jobs.json bullet so future authors don't have to discover
this by hitting the same CWD bug.

Tests:
- ProjectTemplateExampleTemplateTests.siteStatusCheckerParsesAndPlans
  extended to assert the bundled prompt contains {{PROJECT_DIR}}
  UNRESOLVED. If someone accidentally bakes an absolute path into
  the template (their install dir), every user of that template
  would get the wrong path — this test catches that.
- Four new substitution tests in ProjectTemplateInstallerTests:
  resolves PROJECT_DIR / resolves ID + SLUG / leaves unknown tokens
  untouched / substitutes repeated occurrences. All go through the
  static helper directly; no install round-trip needed.

57/57 Swift tests + 24/24 Python tests pass. Catalog check clean.
