docs(changelog): de-dup LaTeX entry and backfill mnemopi/autocomplete fixes

- Remove the stale pre-refinement LaTeX entry left behind when the refined
  #2550 changelog line was applied over the original.
- Add [Unreleased] entries for the two merged farm fixes that shipped without
  one: mnemopi legacy-bank recall isolation (#2412) and slash-command alias
  dedup in the prompt-template autocomplete picker.

 - Fixed `read` on a GitHub commit URL (`github.com/<owner>/<repo>/commit/<sha>`) returning the raw commit HTML page instead of structured content. `parseGitHubUrl` had no `commit` case, so commit URLs fell through to generic HTML rendering; they now resolve via the commits API and render as markdown (subject, author, stats, parents, full commit message, and a per-file unified diff), matching the existing blob/tree/issue/PR handling.
 - Fixed release runs being silently cancelled by a later `main` push, which left tagged versions (`v15.12.6` in the wild) without a GitHub Release or npm publish. The CI workflow's `concurrency` group was `${{ github.workflow }}-${{ github.ref }}`, and since the release-script commit + `v*` tag are pushed atomically to `refs/heads/main`, the release run shared the `CI-refs/heads/main` group with every subsequent push; `cancel-in-progress: true` then killed it before `release_binary` / `release_github` / `release_npm` could run, and no future run carried the release tag at HEAD. The group now resolves to a per-sha `release-<sha>` slot with `cancel-in-progress: false` whenever the push subject matches `chore: bump version to ` (the release-script convention) or `github.ref` is a `v*` tag (`workflow_dispatch` recovery), so release runs are isolated from PR/main churn ([#2564](https://github.com/can1357/oh-my-pi/issues/2564)).
 - Allowed `compat.streamIdleTimeoutMs: 0` in `models.yml`. The schema was `.positive()`, so the documented "set to 0 to disable" escape hatch was only reachable via the global env var ([#2422](https://github.com/can1357/oh-my-pi/issues/2422))

-- Fixed LaTeX math delimiters ($ or $$) and math syntax (such as \text, \times) showing up raw in turn outputs by adding a system prompt instruction to format mathematical equations as clean plain text/Unicode.
 - Fixed LaTeX math delimiters (`$`/`$$`) and commands (such as `\text`, `\times`) rendering raw in the terminal by instructing the model to write equations as plain text / Unicode in its replies. The instruction is scoped to conversational output, so it does not constrain LaTeX or Markdown/KaTeX content the agent is asked to write to files ([#2550](https://github.com/can1357/oh-my-pi/pull/2550) by [@usr-bin-roygbiv](https://github.com/usr-bin-roygbiv)).
 - Fixed the MCP stdio transport `close()` potentially hanging while awaiting a read loop that can block indefinitely; teardown now detaches the read loop instead of awaiting it ([#2550](https://github.com/can1357/oh-my-pi/pull/2550) by [@usr-bin-roygbiv](https://github.com/usr-bin-roygbiv)).
+- Fixed per-project memory isolation pulling other projects' memories into recall. Legacy (pre-#2412) mnemopi banks were rescued into recall when *any* working-memory row tagged the active cwd, but recall reads a bank wholesale and cannot filter rows by cwd, so a mixed-cwd bank leaked unrelated projects' memories. A legacy bank is now rescued only when *every* row tags the active cwd ([#2412](https://github.com/can1357/oh-my-pi/issues/2412)).
+- Fixed a prompt template whose name collides with a builtin slash-command *alias* (e.g. a `models` template beside the builtin `/model`, which owns the `models` alias) appearing as a duplicate entry in the slash-command autocomplete picker. The picker's reserved-name filter now also excludes command aliases, matching runtime resolution (slash commands expand before prompt templates, so the template was already unreachable).
 - Fixed the tool-result renderer re-shaping on every `invalidate()` (spinner tick, stream chunk, resize, keystroke), which made large grep/find/read results block the main thread for seconds and made typing sluggish. `ToolExecutionComponent.#updateDisplay()` now memoizes on a dirty key (result version, expand state, partial flag, spinner frame, image visibility, theme epoch, background-task freeze state, the resolved terminal image protocol, and a display-input version that covers streamed call args, the async edit-diff preview, and Kitty image conversions) and a `#displayBuilt` guard that also fast-paths the `#contentText` fallback, so the O(result-size) shaping runs once per change instead of every frame without freezing streamed args, previews, converted images, a backgrounded task settling to its static form, or images that arrive before the async image-protocol probe resolves. Image-bearing results also re-shape on terminal resize (keyed on the resolved image dimensions only when images are present) so inline images rescale, while image-free results never re-shape on resize ([#2484](https://github.com/can1357/oh-my-pi/issues/2484))
 - Fixed `setTheme()` not bumping the theme epoch on its invalid-theme fallback path: a failed theme load swaps the active theme to the dark fallback, so memoized renderers (the tool-result renderer above) must re-shape — previously they kept the failed theme's stale colors until some other state changed ([#2484](https://github.com/can1357/oh-my-pi/issues/2484))
 - Fixed tool-call spinners animating out of phase across parallel tool calls — each live tool block advanced its glyph from its own per-instance start time, so concurrent spinners showed different frames. Glyphs now derive from a single shared monotonic clock (`sharedSpinnerFrame`), keeping every live block in lockstep.
