Fix DataLayer injection in initialize_examples and fix encryption.md headings

[Copilot]

reset_datalayer(init=True) was reinitializing examples against a potentially different backend than the one it just cleared — initialize_examples() fetched its own get_datalayer() singleton internally, bypassing any injected/overridden DataLayer. notes/encryption.md also used plain-text section labels instead of Markdown headings, causing markdownlint MD022/MD032 failures.

Changes

• vultron/as_vocab/examples/_base.py: initialize_examples() now accepts datalayer: DataLayer | None = None; falls back to get_datalayer() only when no instance is provided.
• vultron/api/v2/routers/datalayer.py: reset_datalayer passes its injected datalayer through to initialize_examples(datalayer=datalayer).
• notes/encryption.md: Converted plain-text section labels to ## headings; added required blank lines before lists.

# Before: always used the singleton, ignoring injected datalayer
def initialize_examples() -> None:
    dl = get_datalayer()
    ...

# After: uses the provided instance when available
def initialize_examples(datalayer: DataLayer | None = None) -> None:
    dl = datalayer if datalayer is not None else get_datalayer()
    ...

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

Fixes a dependency-injection mismatch where reset_datalayer(init=True) could repopulate example data into the global TinyDB singleton instead of the injected DataLayer, and cleans up notes/encryption.md to satisfy markdownlint heading/list rules.

Changes:

• Update initialize_examples() to accept an optional injected DataLayer and only fall back to get_datalayer() when none is provided.
• Pass the injected datalayer through from the reset_datalayer router when init=True.
• Convert plaintext section labels in notes/encryption.md into proper Markdown headings and adjust spacing to address markdownlint failures.

vultron/api/v2/routers/datalayer.py	Ensures reset endpoint initializes examples into the injected datalayer instance.
notes/encryption.md	Replaces section labels with Markdown headings and fixes list spacing for markdownlint compliance.

The init=True branch behavior was changed here (examples now initialized into the injected datalayer). There doesn't appear to be coverage for DELETE /datalayer/reset/?init=true, and this bug would only show up when the dependency injects a non-singleton DataLayer instance. Please add a regression test that overrides the FastAPI dependency to return a separate DataLayer instance (not created via get_datalayer()), calls the reset endpoint with init=true, and asserts the example objects were created in that injected instance (and not in the global singleton).
